What is NetBSD?

The NetBSD Operating System is a fully functional Open Source UNIX-like operating system derived from the University of California, Berkeley Networking Release 2 (Net/2), 4.4BSD-Lite, and 4.4BSD-Lite2 sources. NetBSD runs on many different different system architectures (ports) across a variety of distinct CPU families, and is being ported to more. The NetBSD 9.4 release contains complete binary releases for most of these system architectures, with preliminary support for the others included in source form. Please see the NetBSD website for information on them.

NetBSD is a completely integrated system. In addition to its highly portable, high performance kernel, NetBSD features a complete set of user utilities, compilers for several languages, the X Window System, firewall software and numerous other tools, all accompanied by full source code.

NetBSD is a creation of the members of the Internet community. Without the unique cooperation and coordination the net makes possible, NetBSD would not exist.

Dedication

NetBSD 9.4 is dedicated to the memory of Wayne Knowles, who passed away in December 2022.

Wayne was a long term contributor, working mostly on low level Mips code.

Beyond his technical contributions, Wayne was always helpful and friendly. His example encouraged users to contribute to the project and share their work with the community.

Changes Between The NetBSD 8 and 9 Releases

The NetBSD 9.4 release provides many significant changes, including support for many new devices, hundreds of bug fixes, new and updated kernel subsystems, and numerous userland enhancements. The result of these improvements is a stable operating system fit for production use that rivals most commercially available systems.

It is impossible to completely summarize the massive development that went into the NetBSD 9.4 release. The complete list of changes can be found in the following files:
CHANGES
CHANGES-9.1
CHANGES-9.2
CHANGES-9.3
CHANGES-9.4
files in the top level directory of the NetBSD 9.4 release tree.

Installation and Partitioning Changes
The sysinst installation program has been reworked for this release.

It now supports arbitrary big disks and offers GPT partitions as alternative to MBR/fdisk partitions on a lot architectures.

Unfortunately it has not been tested on all hardware supported by NetBSD. If you have problems partitioning the target disk or installing the system, please report bugs with as much details as possible. See the Administrivia section below on how to report bugs or contact other users and ask for support.

Features to be removed in a later release

The following features are to be removed from NetBSD in the future:

The NetBSD Foundation

The NetBSD Foundation is a tax exempt, not-for-profit 501(c)(3) corporation that devotes itself to the traditional goals and Spirit of the NetBSD Project and owns the trademark of the word ``NetBSD''. It supports the design, development, and adoption of NetBSD worldwide. More information on the NetBSD Foundation, its composition, aims, and work can be found at:

images/
Images (ISO 9660 or USB) for installing NetBSD. Depending on your system, these may be bootable.

source/
Source distribution sets; see below.

In addition to the files and directories listed above, there is one directory per architecture, for each of the architectures for which NetBSD 9.4 has a binary distribution.

The source distribution sets can be found in subdirectories of the source subdirectory of the distribution tree. They contain the complete sources to the system. The source distribution sets are as follows:

gnusrc
This set contains the ``gnu'' sources, including the source for the compiler, assembler, groff, and the other GNU utilities in the binary distribution sets.

sharesrc
This set contains the ``share'' sources, which include the sources for the man pages not associated with any particular program; the sources for the typesettable document set; the dictionaries; and more.

src
This set contains all of the base NetBSD 9.4 sources which are not in gnusrc, sharesrc, or syssrc.

syssrc
This set contains the sources to the NetBSD 9.4 kernel for all architectures as well as the config(1) utility.

xsrc
This set contains the sources to the X Window System.

All the above source sets are located in the source/sets subdirectory of the distribution tree.

The source sets are distributed as compressed tar files. Except for the pkgsrc set, which is traditionally unpacked into /usr/pkgsrc, all sets may be unpacked into /usr/src with the command:
       # cd / ; tar -zxpf set_name.tgz

In each of the source distribution set directories, there are files which contain the checksums of the files in the directory:

MD5
MD5 digests in the format produced by the command:
cksum -a MD5 file.

SHA512
SHA512 digests in the format produced by the command:
cksum -a SHA512 file.

The SHA512 digest is safer, but MD5 checksums are provided so that a wider range of operating systems can check the integrity of the release files.

NetBSD/atari subdirectory structure
The atari-specific portion of the NetBSD 9.4 release is found in the atari subdirectory of the distribution: .../NetBSD-9.4/atari/. It contains the following files and directories:

INSTALL.html
INSTALL.ps
INSTALL.txt
INSTALL.more

Binary distribution sets
The NetBSD atari binary distribution sets contain the binaries which comprise the NetBSD 9.4 release for atari. The binary distribution sets can be found in the atari/binary/sets subdirectory of the NetBSD 9.4 distribution tree, and are as follows:

base
The NetBSD 9.4 atari base binary distribution. You must install this distribution set. It contains the base NetBSD utilities that are necessary for the system to run and be minimally functional.

comp
Things needed for compiling programs. This set includes the system include files (/usr/include) and the various system libraries (except the shared libraries, which are included as part of the base set). This set also includes the manual pages for all of the utilities it contains, as well as the system call and library manual pages.

debug
This distribution set contains debug information for all base system utilities. It is useful when reporting issues with binaries or during developement. This set is huge, if the target disk is small, do not install it.

etc
This distribution set contains the system configuration files that reside in /etc and in several other places. This set must be installed if you are installing the system from scratch, but should not be used if you are upgrading.

games
This set includes the games and their manual pages.

kern-SMALL030, kern-ATARITT, kern-FALCON, kern-HADES, kern-MILAN-ISAIDE, kern-MILAN-PCIIDE
These sets contain a NetBSD/atari 9.4 kernel, named /netbsd. You must install the kernel that matches your hardware.

man
This set includes all of the manual pages for the binaries and other software contained in the base set. Note that it does not include any of the manual pages that are included in the other sets.

misc
This set includes the system dictionaries, the typesettable document set, and other files from /usr/share.

modules
This set includes kernel modules to add functionality to a running system.

rescue
This set includes the statically linked emergency recover binaries installed in /rescue.

text
This set includes NetBSD's text processing tools, including groff(1), all related programs, and their manual pages.

NetBSD maintains its own set of sources for the X Window System in order to assure tight integration and compatibility. These sources are based on X.Org. Binary sets for the X Window System are distributed with NetBSD. The sets are:

xbase
The basic files needed for a complete X client environment. This does not include the X servers.

xcomp
The extra libraries and include files needed to compile X source code.

xdebug
This distribution set contains debug information for all X11 binaries. It is useful when reporting issues with these binaries or during developement. This set is huge, if the target disk is small, do not install it.

xfont
Fonts needed by the X server and by X clients.

xetc
Configuration files for X which could be locally modified.

xserver
The X server.

The atari binary distribution sets are distributed as gzipped tar files named with the extension .tgz, e.g. base.tgz.

The instructions given for extracting the source sets work equally well for the binary sets, but it is worth noting that if you use that method, the filenames stored in the sets are relative and therefore the files are extracted below the current directory. Therefore, if you want to extract the binaries into your system, i.e. replace the system binaries with them, you have to run the tar -xzpf command from the root directory ( / ) of your system.

Additional kernels to those included in the distribution sets may be found in the atari/binary/kernel subdirectory of the NetBSD 9.4 distribution tree. These kernels are generally named something like netbsd-BOOT.gz or some other suitable name. Please note that these kernels are simply gzipped and are not in tar archives.

There are six atari floppy images to be found in the atari/installation/floppies subdirectory of the NetBSD 9.4 distribution. Three of them are bootable TOS kernel floppies and the other three are installation floppies. They are described in more detail below. There are gzipped versions of each available, for easier downloading. (The gzipped versions have the .gz extension added to their names.)

Bootable Kernel floppies
These TOS disks contains the TOS support programs (like loadbsd.ttp and chg_pid.ttp -- see below) and a kernel. They are setup such that you can insert them into your floppy drive, and start the programs from GEM.

For the TT030 and Falcon, the (720 KB) floppy is named boot.fs and the kernel supplied is BOOT. For the Hades, you need the hades-boot.fs floppy (1.44 MB), the kernel is HADES. For the Milan, you need the milan-boot.fs floppy (1.44 MB), the kernel is MILAN-PCIIDE.

Installation floppy:
This disk contains a BSD root file system setup to help you install the rest of NetBSD. This includes formatting and mounting your / (root) and /usr partitions and getting ready to extract (and possibly first fetching) the distribution sets. There is enough on this file system to allow you to make a slip connection, configure an ethernet, mount an NFS file system or ftp. You can also load distribution sets from a SCSI tape or from one of your existing GEMDOS partitions.

The floppies meant for 720 KB disks are named miniroot.fs.1 and miniroot.fs.2. There is also an image for an 1.44 MB disk: miniroot.fs.

There are also TOS utilities in the atari/installation/misc subdirectory, which you will need to get NetBSD/atari up-and-running.

Note:
Each directory in the atari binary distribution also has its own checksum files, just as the source distribution does.

NetBSD/atari System Requirements and Supported Devices

NetBSD/atari 9.4 runs on the TT030, Falcon, Hades and MilanI machines. An FPU is not required. The minimum amount of RAM required is 4 MB. On the Hades, only the Tseng PCI VGA cards (ET4000/ET6000/ET6100) are supported in the 9.4 release. When an unsupported video card is present, you can use NetBSD with a serial console only.

A minimal installation requires around 100MB of disk space, plus a swap partition size of 2*RAM (and always greater than 20MB). You will probably want to compile your own kernel, as GENERIC is large and bulky in order to accommodate all people, BOOT is small and might not have all the features you want).

Supported devices

This list is incomplete by definition. We can not test all SCSI peripherals, ISA cards or PCI cards. If you have problems with such peripherals, please contact the port-atari@NetBSD.org mailing list.

Getting the NetBSD System on to Useful Media

Installation is supported from several media types, including:

No matter what you do, however, you'll need to have three disks handy, on which you will put the install and boot floppy images.

All the images are available from the directory installation/floppies under the root of the NetBSD/atari tree at your favorite archive site.

If you are using NetBSD/atari to make the floppies, you should use the command dd(1) to write the raw floppy images (.fs files) to the disk. As an example, to write the first part of the miniroot file system onto a 720 KB floppy in fd0 use:

       # dd if=miniroot.fs.1 of=/dev/rfd0b bs=9b

If you are using TOS to make the floppies, grab the rawwrite utility from the atari/utils directory and issue the command:


       rawwrite boot.fs

This will create the boot-floppy on the floppy in drive a. The floppies should be pre-formatted on 720 KB / 1.44 MB for both the dd and rawwrite commands to work. Pre-formatting can be best done using the desktop format command. Some other utilities seem to be giving problems.

Since the 1.3 release, it is also possible to use HD-floppies. You should than use the floppy device /dev/rfd0c or add the -H flag to rawwrite.

The steps necessary to prepare the distribution sets for installation depend on which method of installation you choose. The various methods are explained below.

GEMDOS
To install NetBSD from a GEMDOS partition, you need to get the NetBSD distribution sets you wish to install on your system on to a GEMDOS partition.

Note where you placed the files, you will need this later.

Once you have done this, you can proceed to the next step in the installation process, preparing your hard disk.

Tape
To install NetBSD from a tape, you need to somehow get the NetBSD filesets you wish to install on your system on to the appropriate kind of tape. If you make the tape on a UNIX-like system, you can create it as follows:


       # cd .../NetBSD-9.4/atari/binary/sets
       # T=<tape_device>
       # mt -f $T rewind
       # for f in base etc comp games man misc rescue text
       dd if=$f.tgz of=$T conv=osync bs=5k
       # done
       # mt -f $T rewind

where ``<tape_device>'' is the name of the (non-rewinding!) tape device that you're using (probably something like /dev/nrst0, but we make no guarantees 8-). If you can't figure it out, ask your system administrator.

Once you have done this, you can proceed to the next step in the installation process, preparing your hard disk.


Preparing your System for NetBSD installation

Preparing your hard disk for the NetBSD installation.
Note that you will be modifying your hard drives and if you mess something up here you could lose everything on all the drives that you work with. It is therefore advised that you:

If NetBSD has to share the disk with another operating system, you can either take care of partitioning your harddisk before installing NetBSD or delay this until the installer requests you to do it. If you decide to do it now, please create space for at least / (root) and swap partitions. Whatever you decide, take note of the paragraphs below! You need this info to create bootable disks.

Warning:
The AHDI partitioning function erases all partitions on your harddisk even if they are not changed! We know this is rather stupid, but don't say we didn't warn you.

If you want to use an AHDI partitioning scheme and you want to be able to boot directly into NetBSD, there are some constraints on the partition layout.

As you might know, every hard disk has a `root sector' that contains information about the size of the hard disk and the partitions on the hard disk. The root sector can only contain the necessary data for four partitions. Nobody thought that this limitation would cause any problems. After all, 640 KByte should be enough. As hard disks grew, it was necessary to define more than four partitions. In order to be more or less compatible with the old format, a new type of partition entry was defined: XGM partitions.

An XGM partition is a `look over there' sign: Another root sector can be found at the start of the XGM partition. This root sector contains the remaining real partitions. And this is the big mystery: Partitions defined in the root sector of the hard disk are called `primary partitions', partitions defined in the root sector of an XGM partition are called `extended partitions'.

The bootblock will only work if the first NBD partition is a primary partition. This is not a limitation of NetBSD but a limitation of TOS/AHDI: You can only boot from primary partitions.

If you are creating your partitions with HDX, you'll have to be very careful to fulfill this rule. HDX has some very strange ideas when it comes to extended partitions. Fortunately, you can edit this stuff: The ``Edit partition scheme of the unit'' dialog box has a button labeled ``expert''. This button is inactive unless you have defined more than four partitions. Click on it after you have defined the sizes of the partitions.

A new dialog box appears on the screen. The left side contains two blocks of partitions; the upper block always contains the first four partitions, the lower block contains the last three partitions. If you have defined less than 7 partitions, some fields of the lower block will contain the string ``unused''. Some of the partitions will be displayed in reverse video: These are the extended partitions.

The right side contains six possible ranges for the extended partitions. It is not possible to define your own range, you will have to use one of the schemes offered by HDX. To quote from Ghostbusters: Choose and die. The default scheme used by HDX is the first scheme: Extended partitions start with the second partition and end with the second to last partition. If you have defined 7 partitions, partitions #2 to #5 will be extended partitions, while partitions #1, #6 and #7 will be primary partitions.

You can move the extended partition range by clicking on one of the buttons on the right side of the dialog box. Try to find one where your first NetBSD partition is a primary partition. Golden rules:

Booting the installer on an existing system
If you already have NetBSD installed, it is easy. Just boot into single user mode on your current system, or use the shutdown now command to shutdown to single-user mode. Then copy the installer using dd:


       dd if=sysinst.fs of=/dev/rsd0b

where /dev/rsd0b should be the device path of the swap partition your system is configured to use. Once the file is copied, reboot back to the booter and use the '-b' option to make the kernel prompt for a root device. Now enter the swap device as your root device to start the installer.

Booting the installer on new systems.
If your system has more than 6MB RAM, you can skip directly to the section about loadbsd.ttp, since the amount of RAM is enough to load the installer into.

For new new installations on small memory systems, things are a bit more complicated. The easiest way is to mark an AHDI partition as id 'SWP'. You can either accomplish this with HDdriver or use the chg_pid.ttp program supplied on the bootfloppy. To use the fifth partition of your first drive to a swap partition, do the following:


       chg_pid -w 0 4 SWP

As you can see, both the drive and the partition numbers are zero based.

When a swap partition has been created, you can transfer the installer using the file2swp.ttp command, which is also on the bootfloppy. This program copies a (gzipped) file to the first AHDI partition with id 'SWP' on the designated disk. To copy sysinst.fs to your first SCSI disk, use:


       file2swp -w -f sysinst.fs s0

Note that file2swp automatically detects a gzipped file, there is no need for a .gz extension.

Using loadbsd.ttp
To start the installer, you first need to load a NetBSD kernel. This can be done in a couple ways, both of which currently require GEMDOS. You need either the bootfloppy provided in the distribution or you can copy the loadbsd.ttp program and kernel to a boot floppy disk (1.44 MB needed) or put them on a TOS partition. Select the loadbsd program and it will ask for parameters, supply: `-b netbsd' (or whatever name you copied the kernel to). You can, of course, also run it from the shell command-line in MiNT:


       loadbsd -b a:/netbsd

You should see the screen clear and some information about your system as the kernel configures the hardware. Then you will be prompted for a root device. If you copied the installer to a swap partition, as explained above, you have to enter the swap partition as the boot device. When you used your first SCSI disk, this will be sd0b. On the first IDE drive it would be wd0b.

If you didn't copy the installer to swap, you need to use the RAMdisk, so remove the GEMDOS kernel boot floppy from the drive if present and insert the NetBSD install floppy 1. Now enter the name of the boot device depending on the floppy type you have inserted. Use:

The kernel will load the install file system into RAMdisk. While the kernel is loading, it will show a `.' for each track loaded. After loading 80 tracks, it will ask you to insert the next floppy. At this time, insert the NetBSD install floppy 2 and press any key. The kernel continues loading another 40 tracks before it continues to boot.

Installing the NetBSD System

Installing NetBSD is a relatively complex process, but, if you have this document in hand and are careful to read and remember the information which is presented to you by the install program, it shouldn't be too much trouble.

Before you begin, you must have already prepared your hard disk as detailed in the section on preparing your system for install.

The following is a walk-through of the steps necessary to get NetBSD installed on your hard disk.

Running the sysinst installation program

  1. Introduction

    Using sysinst, installing NetBSD is a relatively easy process. Still, you should read this document and have it available during the installation process. This document tries to be a good guide to the installation, and as such, covers many details for the sake of completeness. Do not let this discourage you; the install program is not hard to use.

  2. General

    The following is a walk-through of the steps you will take while installing NetBSD on your hard disk. sysinst is a menu driven program that guides you through the installation process. Sometimes questions will be asked, and in many cases the default answer will be displayed in brackets (``[ ]'') after the question. If you wish to stop the installation, you may press CONTROL-C at any time, but if you do, you'll have to begin the installation process again from scratch by running the /sysinst program from the command prompt. It is not necessary to reboot.

  3. Quick install

    First, let's describe a quick install. The other sections of this document go into the installation procedure in more detail, but you may find that you do not need this. If you want detailed instructions, skip to the next section. This section describes a basic installation, using a CD / DVD as the install media.

  4. Booting NetBSD

    Boot the system as described in the "Booting the installer" section above.

    Once NetBSD has booted and printed all the boot messages, you will be presented with a welcome message and a main menu. It will also include instructions for using the menus.

  5. Network configuration

    If you do not intend to use networking during the installation, but you do want your machine to be configured for networking once it is installed, you should first go to the Utility menu and select the Configure network option. If you only want to temporarily use networking during the installation, you can specify these parameters later. If you are not using the Domain Name System (DNS), you can give an empty response when asked to provide a server.

  6. Installation drive selection and parameters

    To start the installation, select Install NetBSD to hard disk from the main menu.

    The first thing is to identify the disk on which you want to install NetBSD. sysinst will report a list of disks it finds and ask you for your selection. You should see disk names like sd0 or sd1.

  7. Selecting which sets to install

    The next step is to choose which distribution sets you wish to install. Options are provided for full, minimal, and custom installations. If you choose sets on your own, base, etc, and a kernel must be selected.

  8. Partitioning the disk

  9. Editing the NetBSD disklabel

    The partition table of the NetBSD part of a disk is called a disklabel. If your disk already has a disklabel written to it, you can choose Use existing partition sizes. Otherwise, select Set sizes of NetBSD partitions.

    If you want to use NetBSD on an AHDI partitioned disk, you will have to use: Use Existing.

    After you have chosen your partitions and their sizes (or if you opted to use the existing partitions), you will be presented with the layout of the NetBSD disklabel and given one more chance to change it. For each partition, you can set the type, offset and size, block and fragment size, and the mount point. The type that NetBSD uses for normal file storage is called 4.2BSD. A swap partition has a special type called swap. Some partitions in the disklabel have a fixed purpose.

    a
    Root partition (/)

    b
    Swap partition.

    c
    The entire disk.

    d-p
    Available for other use. Traditionally, d is the partition mounted on /usr, but this is historical practice and not a fixed value.

    You will then be asked to name your disk's disklabel. The default response will be ok for most purposes. If you choose to name it something different, make sure the name is a single word and contains no special characters. You don't need to remember this name.

  10. Preparing your hard disk

    You are now at the point of no return. Apart from the changes you made with ahdilabel nothing has been modified on your disk yet. If you confirm that you want to install NetBSD, the partitions now assigned to NetBSD will be actually written to. If you are sure you want to proceed, select yes.

    The install program will now label your disk and create the file systems you specified. The file systems will be initialized to contain NetBSD bootstrapping binaries and configuration files. You will see messages on your screen from the various NetBSD disk preparation tools that are running. There should be no errors in this section of the installation. If there are, restart from the beginning of the installation process. Otherwise, you can continue the installation program after pressing the return key.

  11. Getting the distribution sets

    The NetBSD distribution consists of a number of sets that come in the form of gzipped tar files. At this point, you will be presented with a menu which enables you to choose from one of the following methods of installing the sets. Some of these methods will first transfer the sets to your hard disk, others will extract the sets directly.

    For all these methods, the first step is to make the sets available for extraction. The sets can be made available in a few different ways. The following sections describe each of the methods. After reading about the method you will be using, you can continue to the section labeled `Extracting the distribution sets'.

  12. Installation from CD-ROM

    When installing from a CD-ROM, you will be asked to specify the device name for your CD-ROM drive (usually cd0) and the directory name on the CD-ROM where the distribution files are.

    sysinst will then check that the files are actually present in the specified location and proceed to the extraction of the sets.

  13. Installation using FTP

    To install using ftp, you first need to configure your network setup if you haven't already done so. sysinst will help you with this, asking if you want to use DHCP. If you do not use DHCP, you can enter network configuration details yourself. If you do not have DNS set up for the machine that you are installing on, you can just press RETURN in answer to this question, and DNS will not be used.

    You will also be asked to specify the host that you want to transfer the sets from, the directory on that host, the account name and password used to log into that host using ftp, and optionally a proxy server to use. If you did not set up DNS, you will need to specify an IP address instead of a hostname for the ftp server.

    sysinst will then transfer the set files from the remote site to your hard disk.

  14. Installation using NFS

    To install using NFS, you first need to configure your network setup if you haven't already done so. sysinst will do this for you, asking you if you want to use DHCP. If you do not use DHCP, you can enter network configuration details yourself. If you do not have DNS set up for the machine that you are installing on, you can just press RETURN in answer to this question, and DNS will not be used.

    You will also be asked to specify the host that you want to transfer the sets from and the directory on that host that the files are in. This directory should be mountable by the machine you are installing on, i.e., correctly exported to your machine.

    If you did not set up DNS, you will need to specify an IP address instead of a hostname for the NFS server.

  15. Installation from an unmounted file system

    In order to install from a local file system, you will need to specify the device that the file system resides on (for example wd1e), the type of the file system, and the directory on the specified file system where the sets are located. sysinst will then check if it can indeed access the sets at that location.

  16. Installation from a local directory

    This option assumes that you have already done some preparation yourself. The sets should be located in a directory on a file system that is already accessible. sysinst will ask you for the name of this directory.

  17. Extracting the distribution sets

    A progress bar will be displayed while the distribution sets are being extracted.

    After all the files have been extracted, the device node files will be created. If you have already configured networking, you will be asked if you want to use this configuration for normal operation. If so, these values will be installed in the network configuration files.

  18. Configure additional items

    The next menu will allow you to select a number of additional items to configure, including the time zone that you're in, to make sure your clock has the right offset from UTC, the root user's shell, and the initial root password.

    You can also enable installation of binary packages, which installs the pkgin(1) tool for managing binary packages for third-party software. This will feel familiar to users of package tools such as apt-get or yum. If you prefer to install third-party software from source, you can install the pkgsrc(7) tree.

    Finally, you can enable some daemons such as sshd(8), ntpd(8), or mdnsd(8).

  19. Finalizing your installation

    Congratulations, you have successfully installed NetBSD 9.4. You can now reboot the machine and boot NetBSD from hard disk.


Post installation steps

Once you've got the operating system running, there are a few things you need to do in order to bring the system into a properly configured state. The most important steps are described below.

  1. Before all else, read postinstall(8).

  2. Configuring /etc/rc.conf

    If you or the installation software haven't done any configuration of /etc/rc.conf (sysinst normally will), the system will drop you into single user mode on first reboot with the message

           /etc/rc.conf is not configured. Multiuser boot aborted.

    and with the root file system (/) mounted read-only. When the system asks you to choose a shell, simply press RETURN to get to a /bin/sh prompt. If you are asked for a terminal type, respond with vt220 (or whatever is appropriate for your terminal type) and press RETURN. You may need to type one of the following commands to get your delete key to work properly, depending on your keyboard:
           # stty erase '^h'
           # stty erase '^?'
    At this point, you need to configure at least one file in the /etc directory. You will need to mount your root file system read/write with:
           # /sbin/mount -u -w /
    Change to the /etc directory and take a look at the /etc/rc.conf file. Modify it to your tastes, making sure that you set rc_configured=YES so that your changes will be enabled and a multi-user boot can proceed. Default values for the various programs can be found in /etc/defaults/rc.conf, where some in-line documentation may be found. More complete documentation can be found in rc.conf(5).

    When you have finished editing /etc/rc.conf, type exit at the prompt to leave the single-user shell and continue with the multi-user boot.

    Other values that may need to be set in /etc/rc.conf for a networked environment are hostname and possibly defaultroute. You may also need to add an ifconfig_int for your <int> network interface, along the lines of


           ifconfig_le0="inet 192.0.2.123 netmask 255.255.255.0"

    or, if you have myname.my.dom in /etc/hosts:


           ifconfig_le0="inet myname.my.dom netmask 255.255.255.0"

    To enable proper hostname resolution, you will also want to add an /etc/resolv.conf file or (if you are feeling a little more adventurous) run named(8). See resolv.conf(5) or named(8) for more information.

    Instead of manually configuring networking, DHCP can be used by setting dhcpcd=YES in /etc/rc.conf.

  3. Select the proper terminal devices

    You will have to edit the /etc/ttys file. If you don't have a Milan, you must disable the ttyEx devices. For the Milan, you will have to disable the ttyex devices. This is easy, just change 'on' to 'off' on the corresponding lines.

  4. Logging in

    After reboot, you can log in as root at the login prompt. If you didn't set a password in sysinst, there is no initial password. You should create an account for yourself (see below) and protect it and the ``root'' account with good passwords. By default, root login from the network is disabled (even via ssh(1)). One way to become root over the network is to log in as a different user that belongs to group ``wheel'' (see group(5)) and use su(1) to become root.

  5. Adding accounts

    Use the useradd(8) command to add accounts to your system. Do not edit /etc/passwd directly! See vipw(8) and pwd_mkdb(8) if you want to edit the password database.

  6. The X Window System

    If you installed the X Window System, you may want to read the chapter about X in the NetBSD Guide:

  7. Installing third party packages

    If you wish to install any of the software freely available for UNIX-like systems you are strongly advised to first check the NetBSD package system, pkgsrc. pkgsrc automatically handles any changes necessary to make the software run on NetBSD. This includes the retrieval and installation of any other packages the software may depend upon.

  8. Misc

Upgrading a previously-installed NetBSD System

The easiest way to upgrade to NetBSD 9.4 is with binaries, and that is the method documented here.

To do the upgrade, you must first boot the system as described in the Booting the installer section. You must also have at least the base and kern binary distribution sets available. Finally, you must have sufficient disk space available to install the new binaries. Since files already installed on the system are overwritten in place, you only need additional free space for files which weren't previously installed or to account for growth of the sets between releases.

Since upgrading involves replacing the kernel, boot blocks, and most of the system binaries, it has the potential to cause data loss. You are strongly advised to back up any important data on the NetBSD partition or on another operating system's partition on your disk before beginning the upgrade process.

The upgrade procedure is similar to an installation, but without the hard disk partitioning.

Fetching the binary sets is done in the same manner as the installation procedure; refer to the installation part of the document for help. File systems are checked before unpacking the sets.

After a new kernel has been copied to your hard disk, your machine is a complete NetBSD 9.4 system. However, that doesn't mean that you're finished with the upgrade process. You will probably want to update the set of device nodes you have in /dev. If you've changed the contents of /dev by hand, you will need to be careful about this, but if not, you can just cd into /dev, and run the command:

       # sh MAKEDEV all

sysinst will attempt to merge the settings stored in your /etc directory with the new version of NetBSD using the postinstall(8) utility. However, postinstall(8) is only able to deal with changes that are easily automated. It is recommended that you use the etcupdate(8) tool to merge any remaining configuration changes.

Compatibility Issues With Previous NetBSD Releases

Users upgrading from previous versions of NetBSD may wish to bear the following problems and compatibility issues in mind when upgrading to NetBSD 9.4.

Note that sysinst will automatically invoke

postinstall fix
and thus all issues that are fixed by postinstall by default will be handled.

A number of things have been removed from the NetBSD 9.4 release. See the ``Components removed from NetBSD'' section near the beginning of this document for a list.

Using online NetBSD documentation

Documentation is available if you installed the manual distribution set. Traditionally, the ``man pages'' (documentation) are denoted by `name(section)'. Some examples of this are

The section numbers group the topics into several categories, but three are of primary interest: user commands are in section 1, file formats are in section 5, and administrative information is in section 8.

The man command is used to view the documentation on a topic, and is started by entering man [section] topic. The brackets [] around the section should not be entered, but rather indicate that the section is optional. If you don't ask for a particular section, the topic with the lowest numbered section name will be displayed. For instance, after logging in, enter


       # man passwd

to read the documentation for passwd(1). To view the documentation for passwd(5), enter


       # man 5 passwd

instead.

If you are unsure of what man page you are looking for, enter


       # apropos subject-word

where subject-word is your topic of interest; a list of possibly related man pages will be displayed.

If you've got something to say, do so! We'd like your input. There are various mailing lists available via the mailing list server at majordomo@NetBSD.org. See
       https://www.NetBSD.org/mailinglists/
for details.

There are various mailing lists set up to deal with comments and questions about this release. Please send comments to: netbsd-comments@NetBSD.org.

To report bugs, use the send-pr(1) command shipped with NetBSD, and fill in as much information about the problem as you can. Good bug reports include lots of details.

Bugs also can be submitted and queried with the web interface at
       https://www.NetBSD.org/support/send-pr.html

There are also port-specific mailing lists, to discuss aspects of each port of NetBSD. Use majordomo to find their addresses, or visit
       https://www.NetBSD.org/mailinglists/

If you're interested in doing a serious amount of work on a specific port, you probably should contact the `owner' of that port (listed below).

If you'd like to help with NetBSD, and have an idea as to how you could be useful, send us mail or subscribe to: netbsd-users@NetBSD.org.

As a favor, please avoid mailing huge documents or files to these mailing lists. Instead, put the material you would have sent up for FTP or WWW somewhere, then mail the appropriate list about it. If you'd rather not do that, mail the list saying you'll send the data to those who want it.
