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 57 different system architectures (ports) across 15 distinct CPU families, and is being ported to more. The NetBSD 6.0.3 release contains complete binary releases for many different system architectures. (A few ports are not fully supported at this time and are thus not part of the binary distribution. Please see the NetBSD web site at http://www.NetBSD.org/ 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, it's likely that NetBSD wouldn't exist.
The complete list of changes can be found in the CHANGES-6.0.3: http://ftp.NetBSD.org/pub/NetBSD/NetBSD-6.0.3/CHANGES-6.0.3 file in the top level directory of the NetBSD 6.0.3 release tree. An abbreviated list is as follows:

The root directory of the NetBSD 6.0.3 release is organized as follows:
In addition to the files and directories listed above, there is one directory per architecture, for each of the architectures for which NetBSD 6.0.3 has a binary distribution.
The source distribution sets can be found in subdirectories of the
subdirectory of the distribution tree.
They contain the complete sources to the system.
The source distribution sets are as follows:
All the above source sets are located in the
subdirectory of the distribution tree.
The source sets are distributed as compressed tar files.
Except for the
set, which is traditionally unpacked into
all sets may be unpacked into
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:
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.

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:
The rs6000 binary distribution sets are distributed as gzipped tar files
named with the extension
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
command from the root directory (
) of your system.
Since NetBSD/rs6000 is an experimental port, the hardware support is in a constant state of flux. Check the port-prep@NetBSD.org mailing list and the NetBSD/rs6000 port homepage for an up-to-date list of known supported hardware. http://www.NetBSD.org/ports/rs6000/
6.0.3 works diskless via netboot.
Installation is supported from several media types, including:
The steps necessary to prepare the distribution sets for installation depend upon which installation medium you choose. The steps for the various media are outlined below.
Proceed to the instructions on installation.
Once you have this information, you can proceed to the next step in the installation or upgrade process. If you're installing NetBSD from scratch, go to the section on preparing your hard disk, below. If you're upgrading an existing installation, go directly to the section on upgrading.
/etc/exportsfile on the NFS server and resetting its mount daemon (mountd). (Both of these actions will probably require superuser privileges on the server.)
You need to know the numeric IP address of the NFS server, and, if you don't have DHCP available on your network and the server is not on a network directly connected to the machine on which you're installing or upgrading NetBSD, you need to know the numeric IP address of the router closest to the NetBSD machine. Finally, you need to know the numeric IP address of the NetBSD machine itself.
Once the NFS server is set up properly and you have the information mentioned above, you can proceed to the next step in the installation or upgrade process. If you're installing NetBSD from scratch, go to the section on preparing your hard disk, below. If you're upgrading an existing installation, go directly to the section on upgrading.
If you're making the tape on a UNIX-like system, the easiest way to do so is probably something like:

distributions on tape (in
order to do the absolute minimum installation to a new disk),
you would do the following:
# cd .../NetBSD-6.0.3
# cd rs6000/binary
# tar -cf tape_device kern-GENERIC base etc
Once you have the files on the tape, you can proceed to the next step in the installation or upgrade process. If you're installing NetBSD from scratch, go to the section on preparing your hard disk, below. If you're upgrading an existing installation, go directly to the section on upgrading.
To netboot a rs6000, you must configure one or more servers to provide
information and files to your rs6000 (the
If you are using
(any architecture) on your netboot server(s), the information
provided here should be sufficient to configure everything.
Additionally, you may wish to look at the
manual page and the manual pages for each daemon you'll be configuring.
If the server(s) are another operating system, you should consult the
NetBSD Diskless HOW-TO, which will walk you through the steps necessary to
configure the netboot services on a variety of platforms.
You may either netboot the installer so you can install onto a locally attached disk, or you may run your system entirely over the network.
Briefly, the netboot
process involves discovery, bootstrap, kernel and file system stages.
In the first stage, the client discovers information
about where to find the bootstrap program.
Next, it downloads and executes the bootstrap program.
The bootstrap program goes through another discovery phase to determine
where the kernel is located.
The bootstrap program tries to mount the NFS share containing the kernel.
Once the kernel is loaded, it starts executing.
For RAM disk kernels, it mounts the RAM disk file system and begins
executing the installer from the RAM disk.
For normal (non-RAM disk) kernels, the
kernel tries to mount the NFS share that had the kernel and starts
the installation tools or
TFTP is used in the bootstrap phase to download
NFS is used in both the kernel and file system stages to download the
kernel, and to access files on the file server.
We will use
as the MAC address (ethernet hardware address) of your netboot client
You should have determined this address in an earlier stage.
In this example, we will use
as the IP address of your client and
as its name.
We will assume you're providing all of your netboot services
on one machine called
with the client's files exported from the directory
You should, of course, replace all of these with the names, addresses,
and paths appropriate to your environment.
You should set up each netboot stage in order (i.e., discovery, bootstrap, kernel, and then file system) so that you can test them as you proceed.
The default configuration of the TFTP server is to run in a
environment in the
Thus, the first order of business is to create this directory:
# mkdir -p /tftpboot
and uncomment the line with the TFTP daemon:
tftp dgram udp wait root /usr/libexec/tftpd tftpd -l -s /tftpboot
If the server is running
you can achieve this with:
# /etc/rc.d/inetd restart
Now, you need to copy the
for your rs6000 machine to
Just to be sure, let's make everything readable.
# chmod -R a+rX /tftpboot
table gets messed up, and the TFTP server can't communicate with the
In this case, it will write a log message (via
tftpd: write: Host is down'.
If this is the case, you may need to force the server to map your client's
ethernet address to its IP address:
# arp -s client CC:CC:CC:CC:CC:CC
Now your system should be able to load the bootstrap program and start looking for the kernel. Let's set up the NFS server. Create the directory you are exporting for the netboot client:
# mkdir -p /export/client/root
Put the following line in
to enable NFS sharing:
/export/client/root -maproot=root client.test.net
If your server is currently running an NFS server, you only need to
Otherwise, you need to start
If the server is running
you can achieve this with:
# /etc/rc.d/rpcbind start # /etc/rc.d/nfsd start # /etc/rc.d/mountd restart
Now, if you place a kernel named
your client should boot the kernel.
You can skip this step if you do not plan to run your client diskless after installation. Otherwise, you need to extract and set up the client's installation of NetBSD. The Diskless HOW-TO describes how to provide better security and save space on the NFS server over the procedure listed here. See http://www.NetBSD.org/docs/network/netboot/nfs.html for details.
# cd /export/client/root # tar -xpzf /path/to/files/base.tgz # tar -xpzf /path/to/files/etc.tgz
Continue with the other non-essential distribution sets if desired.
# mkdir /export/client/root/swap # dd if=/dev/zero of=/export/client/swap bs=4k count=4k # echo '/export/client/swap -maproot=root:wheel client.test.net' | cat >> /etc/exports # /etc/rc.d/mountd restart
# cd /export/client/root/dev # ./MAKEDEV all
This procedure only works on NetBSD hosts.
Create a file in
with the following lines:
server:/export/client/swap none swap sw,nfsmntpt=/swap server:/export/client/root / nfs rw 0 0
rc_configured=YES hostname="client" defaultroute="192.168.1.1" nfs_client=YES auto_ifconfig=NO net_interfaces=""
Make sure rc does not reconfigure the network device since it will lose its connection to the NFS server with your root file system.
::1 localhost 127.0.0.1 localhost 192.168.1.10 client.test.net client 192.168.1.5 server.test.net server
If you want
these services to start up every time you boot
your server, make sure the following lines are present in your
nfs_server=YES # enable server daemons mountd=YES rpcbind=YES rpcbind_flags="-l" # -l logs libwrap
Also, you'll need to make sure the

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 on which the software may depend.

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.confis correctly configured, you can install them with the following commands:
# pkgin install tcsh # pkgin install bash # pkgin install perl # pkgin install apache # pkgin install kde # pkgin install firefox ...
The above commands will install the Tenex-csh and Bourne Again shells, the Perl programming language, Apache web server, KDE desktop environment and the Firefox web browser as well as all the packages they depend on.
pkgsrc(7)framework for compiling packages can be obtained by retrieving the file ftp://ftp.NetBSD.org/pub/pkgsrc/pkgsrc.tar.gz. It is typically extracted into
/usr/pkgsrc(though other locations work fine) with the commands:
# cd /usr
# tar -zxpf pkgsrc.tar.gz
After extracting, see the

The easiest way to upgrade to NetBSD 6.0.3 is with binaries, and that is the method documented here.
To do the upgrade, you must have one form of boot media available.
You must also have at least the
binary distribution sets available.
Finally, you must have sufficient disk space available to install the
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.
If you have a few megabytes free on each of your root
partitions, you should have enough space.
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.
