FreeBSD 8.1-RELEASE is now available for the amd64, i386, ia64, pc98, powerpc, and sparc64 architectures.

FreeBSD 8.1 can be installed from bootable ISO images or over the network. Some architectures (currently amd64 and i386) also support installing from a USB memory stick. The required files can be downloaded via FTP or BitTorrent as described in the sections below. While some of the smaller FTP mirrors may not carry all architectures, they will all generally contain the more common ones such as amd64 and i386.

MD5 and SHA256 hashes for the release ISO images are included at the bottom of this message.

The purpose of the images provided as part of the release are as follows:


This contains everything necessary to install the base FreeBSD operating system, a collection of pre-built packages, and the documentation. It also supports booting into a "livefs" based rescue mode. This should be all you need if you can burn and use DVD-sized media.


This contains the base FreeBSD operating system and the documentation packages for CDROM-sized media. There are no other packages.


This contains support for booting into a "livefs" based rescue mode but does not support doing an install from the CD itself. It is meant to help rescue an existing system but could be used to do a network based install if necessary.


This supports booting a machine using the CDROM drive but does not contain the support for installing FreeBSD from the CD itself. You would need to perform a network based install (e.g. from an FTP server) after booting from the CD.


This can be written to an USB memory stick (flash drive) and used to do an install on machines capable of booting off USB drives. It also supports booting into a "livefs" based rescue mode. The documentation packages are provided but no other packages.

As one example of how to use the memstick image, assuming the USB drive appears as /dev/da0 on your machine something like this should work:

# dd if="8".1-RELEASE-amd64-memstick.img of=/dev/da0 bs="10240" conv="sync"

Be careful to make sure you get the target (of=) correct.

FreeBSD 8.1-RELEASE can also be purchased on CD-ROM or DVD from several vendors. One of the vendors that will be offering FreeBSD 8.1-based products is:


8.1-RELEASE ISOs are available via BitTorrent. A collection of torrent files to download the images is available at:


At the time of this announcement the following FTP sites have FreeBSD 8.1-RELEASE available.

However before trying these sites please check your regional mirror(s) first by going to:

  • ftp://ftp.<yourdomain>

Any additional mirror sites will be labeled ftp2, ftp3 and so on.

More information about FreeBSD mirror sites can be found at:

Updates from Source

The procedure for doing a source code based update is described in the FreeBSD Handbook:

The branch tag to use for updating the source is RELENG_8_1 for CVS. For SVN use releng/8.1.

FreeBSD Update

The freebsd-update(8) utility supports binary upgrades of i386 and amd64 systems running earlier FreeBSD releases. Systems running 7.[0123]-RELEASE, 8.0-RELEASE, 8.1-BETA1, or 8.1-RC[12] can upgrade as follows:

# freebsd-update upgrade -r 8.1-RELEASE

During this process, FreeBSD Update may ask the user to help by merging some configuration files or by confirming that the automatically performed merging was done correctly.

# freebsd-update install

The system must be rebooted with the newly installed kernel before continuing.

# shutdown -r now

After rebooting, freebsd-update needs to be run again to install the new userland components, and the system needs to be rebooted again:

# freebsd-update install

At this point, users of systems being upgraded from FreeBSD 7.3-RELEASE or earlier will be prompted by freebsd-update to rebuild all third-party applications (e.g., ports installed from the ports tree) due to updates in system libraries.

After updating installed third-party applications (and again, only if freebsd-update printed a message indicating that this was necessary), run freebsd-update again so that it can delete the old (no longer used) system libraries:

# freebsd-update install

Finally, reboot into 8.1-RELEASE:

# shutdown -r now


The FreeBSD Security Team has designated FreeBSD 8.1 an "Extended" support release and currently plans to support FreeBSD 8.1 until July 31, 2012. For more information on the Security Team and their support of the various FreeBSD branches see:


Many companies donated equipment, network access, or man-hours to support the release engineering activities for FreeBSD 8.1 including The FreeBSD Foundation, Hewlett-Packard, Yahoo!, NetApp, Internet Systems Consortium, and Sentex Communications.
