What is NetBSD?

The NetBSD Operating System is a fully functional open-source 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 10.0_RC2 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 10.0 is dedicated to the memory of Ryo SHIMIZU, who passed away in May 2023.

Ryo's technical contributions are too many to list here in full. He was a long term contributor and worked on a lot of low-level code over various architectures, from x68k to aarch64. He also worked on various out-of-tree NetBSD items, like the IIJ git repository conversion.

The project lost an excellent technical contributor and many of us a good friend.

Changes Between The NetBSD 9 and 10 Releases

The NetBSD 10.0_RC2 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.

One important new feature in this release is the support for extended attributes and access controll lists on FFS file systems.

For new installations the installer will default to disable this features, so the file system is compatible with older NetBSD releases (before 10), and allow other operating systems to mount this file systems at least in read-only mode.

If you want a new installed file system to support extended attributes, change the file system type from ``FFSv2'' to ``FFSv2ea'' in the partitioning menu. You can also convert file systems later, using the fsck_ffs(8) utility. More details are available in this guide.

If you are upgrading from a version of NetBSD-current please also check the Compatibility Issues With Previous NetBSD Releases.

It is impossible to completely summarize the massive development that went into the NetBSD 10.0_RC2 release. The complete list of changes can be found in the following files:

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 10.0_RC2 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 10.0_RC2 sources which are not in gnusrc, sharesrc, or syssrc.

syssrc
This set contains the sources to the NetBSD 10.0_RC2 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/evbarm subdirectory structure
The evbarm-specific portion of the NetBSD 10.0_RC2 release is found in the evbarm subdirectory of the distribution: .../NetBSD-10.0_RC2/evbarm/. It contains the following files and directories:

Binary distribution sets
The NetBSD 10.0_RC2 release for evbarm is comprised of the following binary sets, which can be found in the evbarm/binary/sets subdirectory of the NetBSD 10.0_RC2 distribution tree:

base
The NetBSD 10.0_RC2 evbarm 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 development. This set is huge, if the target disk is small, do not install it.

dtb
Devicetree hardware descriptions for specific boards.

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.

gpufw
This set includes firmware for graphical drivers.

kern-GENERIC
This set contains a NetBSD/evbarm 10.0_RC2 GENERIC kernel, named /netbsd. You must install this distribution set.

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 development. 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. This includes the modular X.Org server.

The evbarm binary distribution sets are distributed as tar files compressed with gzip 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.

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

NetBSD/evbarm System Requirements and Supported Devices

32-bit SoCs supported by GENERIC kernels (Armv7-A)

QEMU is also supported.

For a full list of supported devicetree-based boards, see the contents of the dtb.tgz set.

64-bit SoCs supported by GENERIC64 kernels

Devices conforming to the Arm "ServerReady" (SBBR and SBSA) specifications, and QEMU are also supported.

For a full list of supported devicetree-based boards, see the contents of the dtb.tar.xz set.

Getting the NetBSD System on to Useful Media

Generally, NetBSD is installed on Arm devices by writing a live image (armv7.img, or arm64.img for 64-bit devices) to a SD card or USB device. For Armv6 Raspberry Pi 1s, this image is rpi.img.gz. The storage device should be at least 2GB.

If you're on Windows rather than a Unix variant, you can use rawrite32 instead of dd(1) to write images, and 7-Zip to decompress .gz files.

Arm devices generally also ship with a vendor-specific U-Boot bootloader, which may be replaced with a board-specific "mainline" U-Boot image from pkgsrc for an optimal NetBSD experience.

Preparing your System for NetBSD installation

After writing an SD card image, there are generally no specific preparation steps needed for Arm.

Once the system is booted, the init system will resize the root partition to take up the entire disk. Afterwards, the system can be configured to your liking.

Installing the NetBSD System

Installation for Armv7 and AArch64 devices with U-Boot
Installing NetBSD/evbarm to a SATA hard disk
Some Arm boards offer a SATA interface, and you might want to install NetBSD to a hard disk after you've got it running from an SD card. You can do this using sysinst(8) from within NetBSD.

There are instructions for using sysinst on Arm on the NetBSD wiki. The main difference from installing on other ports is that a FAT32 partition is required for /boot.

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_awge0="inet 192.0.2.123 netmask 255.255.255.0"

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


           ifconfig_awge0="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. 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.

  4. 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.

  5. The X Window System

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

  6. 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.

  7. Misc

Upgrading a previously-installed NetBSD System

The easiest way to upgrade to NetBSD evbarm 10.0_RC2 is by using the sysutils/sysupgrade package from pkgsrc.

First, edit /usr/pkg/etc/sysupgrade.conf. Make sure RELEASEDIR and ARCHIVE_EXTENSION are correct:

# Replace evbarm-aarch64 with evbarm-earmv7hf on a 32-bit system, evbarm-earmv6hf on the original RPI
RELEASEDIR="https://cdn.netbsd.org/pub/NetBSD/NetBSD-10.0_RC2/evbarm-aarch64/"
ARCHIVE_EXTENSION=tar.xz

Make sure /boot is mounted, and copy the new board-specific *.dts device tree file into place. Note that the device tree files are sorted into SoC-type subdirectories in /boot/dtb, e.g. allwinner, amlogic, broadcom, freescale, nvidia, rockchip.

For example, for the Allwinner-based PINE A64 LTS:

$ ftp https://cdn.netbsd.org/pub/NetBSD/NetBSD-10.0_RC2/evbarm-aarch64/binary/sets/dtb.tar.xz
$ unxz dtb.tar.xz
# cp ./boot/dtb/allwinner/sun50i-a64-pine64-lts.dtb /boot/dtb/allwinner/
Also copy bootaa64.efi if applicable:
$ ftp https://cdn.netbsd.org/pub/NetBSD/NetBSD-10.0_RC2/evbarm-aarch64/installation/misc/bootaa64.efi
# cp bootaa64.efi /boot/EFI/BOOT/bootaa64.efi

Finally:

# sysupgrade fetch
# sysupgrade kernel
# sysupgrade modules
# reboot
# sysupgrade sets
# sysupgrade etcupdate
# sysupgrade postinstall
# reboot

This is the most careful possible path with sysupgrade that makes sure the kernel and userland are always fully compatible, by making sure the kernel and boot files are newer than the userland. It is also possible to:

# sysupgrade auto
# reboot

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 10.0_RC2.

Note that sysinst will automatically invoke

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

In NetBSD9 and earlier, filesystems listed in /etc/fstab would be mounted before non-legacy zfs filesystems. Starting from NetBSD10 this order has been reversed.

If you have ever run a version of NetBSD-current between April 18, 2020 and September 23, 2022 (the version numbers used in the affected time range are between 9.99.56 and 9.99.106) your FFS file systems might have broken extended attributes stored.

You should follow this guide before booting the updated system multi-user for the first time.

Note that you do not need to do anything special if you never did run any affected kernel, especially if you have never run NetBSD-current.

The display drivers used for modern GPUs and the whole subsystem supporting it (DRM/KMS) have been updated to a newer version. Unfortunately not all issues with this have been resolved before the NetBSD10.0 release. You can find a list of issues in the Open issues with new DRM/KMS section of the release engineering wiki page.

A number of things have been removed from the NetBSD 10.0_RC2 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.

Administrivia

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.
