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.
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.
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:

The root directory of the NetBSD 10.0_RC2 release is organized as follows:
.../NetBSD-10.0_RC2/
CHANGESCHANGES-10.0CHANGES.prevLAST_MINUTEREADME.filesimages/source/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:
config(1)
utility.
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:
MD5SHA512The 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 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:
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.
QEMU is also supported.
For a full list of supported devicetree-based boards, see the
contents of the
dtb.tgz
set.
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.
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.
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.
gunzip(1)
on Unix.
# dd if=armv7.img of=/dev/rld0 bs=1m conv=sync progress=1
sysutils/u-boot-*
packages in
pkgsrc.
If you're using pkgsrc on an UNIX-like operating system that isn't NetBSD,
you must bootstrap first (see the
README
file in the root directory of pkgsrc).
You can also extract the U-Boot image from u-boot-*.tgz archive in an existing NetBSD binary package set.
Install the board-specific U-Boot to the SD card,
e.g. for Allwinner devices (PINE H64 in this case):
# dd if=/usr/pkg/share/u-boot/pine-h64/u-boot-sunxi-with-spl.bin of=/dev/rld0 bs=1k seek=8 conv=sync progress=1
Or a Rockchip device (e.g. RockPro64):
# dd if=/usr/pkg/share/u-boot/rockpro64/rksd_loader.img of=/dev/rld0 seek=64 conv=sync progress=1
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.
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.
postinstall(8).
/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.
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.
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.
If you installed the X Window System, you may want to read the chapter about X in the NetBSD Guide:
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.
evbarm/10.0_RC2/All
subdir.
If you installed
pkgin(1)
in the
sysinst
post-installation configuration menu, you can use it to automatically install
binary packages over the network.
Assuming that
/usr/pkg/etc/pkgin/repositories.conf
is correctly configured, you can install them with the following commands:
# pkgin install tcsh bash perl apache xfce4 firefox ...
The above command will install the Tenex-csh and Bourne Again shells, the Perl programming language, Apache web server, Xfce desktop environment and the Firefox web browser as well as all the packages they depend on.
If it was not automatically installed,
pkgin(1)
can be installed on a fresh
NetBSD
system with
pkg_add(1):
export PKG_PATH=https://cdn.netbsd.org/pub/pkgsrc/packages/NetBSD/$(uname -p)/$(uname -r | cut -d_ -f1)/All pkg_add pkgin
pkgsrc(7)
framework for compiling packages and did not install it from the
sysinst(8)
post-installation configuration menu, you can obtain it by retrieving
the file
/usr/pkgsrc
(though other locations work fine) with the commands:
# cd /usr
# tar -zxpf pkgsrc.tar.gz
After extracting, see the
doc/pkgsrc.txt
file in the extraction directory (e.g.,
/usr/pkgsrc/doc/pkgsrc.txt)
for more information.
/etc/mail/aliases
to forward root mail to the right place.
Don't forget to run
newaliases(1)
afterwards.
/etc/rc.local
to run any local daemons you use.
/etc
files are documented in section 5 of the manual; so just invoking
# man 5 filename
is likely to give you more information on these files.
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:
Also copy
$ 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/
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
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
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.
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
intro(1),
man(1),
apropos(1),
passwd(1),
and
passwd(5).
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!
