FreeBSD 6.4-RELEASE Announcement

Date: November 28, 2008

The FreeBSD Release Engineering Team is pleased to announce the availability of FreeBSD 6.4-RELEASE. At this time 6.4-RELEASE is expected to be the last of the 6-STABLE releases. Some of the highlights:

  • New and much-improved NFS Lock Manager (NLM) client

  • Support for the Camellia cipher

  • boot loader changes allow, among other things, booting from USB devices and booting from GPT-labeled devices with GPT-enabled BIOSes

  • DVD install ISO images for amd64/i386

  • KDE updated to 3.5.10, GNOME updated to 2.22.3

  • Updates for BIND, sendmail, OpenPAM, and others

For a complete list of new features and known problems, please see the online release notes and errata list, available at:

The FreeBSD Security Team intends to support 6.4-RELEASE until November 30th, 2010.


FreeBSD 6.4-RELEASE is now available for the amd64, i386, pc98, and sparc64 architectures. The builds for the alpha architecture have not completed yet and will be announced later. FreeBSD 6.4-RELEASE can be installed from bootable ISO images or over the network; 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 i386 and amd64.

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

The contents of the ISO images provided as part of the release has changed for most of the architectures. Using the i386 architecture as an example, there are ISO images named "bootonly", "disc1", "disc2", "disc3", "docs", and "dvd1". The "bootonly" image is suitable for booting a machine to do a network based installation using FTP or NFS. The "disc1", "disc2", and "disc3" images are CDROM-sized (700MB media) and are used to do a full installation that includes a basic set of packages and does not require network access to an FTP or NFS server during the installation. In addition, "disc1" supports booting into a "live CD-based filesystem" and system rescue mode. The "docs" image has all of the documentation for all supported languages. The "dvd1" image is DVD-sized and includes everything that is on the CDROM discs. So "dvd1" can be used to do a full installation that includes a basic set of packages, it has all of the documentation for all supported languages, and it can be used for booting into a "live CD-based filesystem" and system rescue mode. Most people will find that "disc1", "disc2" and "disc3" are all that are needed if their machine does not have a DVD-capable drive. For people with machines that do have a DVD-capable drive "dvd1" should be all that is required. If you intend to install ports from source instead of using the pre-built packages included with the release only "disc1" is needed.

FreeBSD 6.4-RELEASE can also be purchased on CD-ROM from several vendors. One of the vendors that will be offering FreeBSD 6.4-based products is:


6.4-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 6.4-RELEASE available.

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


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

FreeBSD Update

The freebsd-update(8) utility supports binary upgrades of i386 and amd64 systems running earlier FreeBSD releases. Systems running 6.3-RELEASE, 6.4-BETA, 6.4-RC1, or 6.4-RC2 can upgrade as follows:

# freebsd-update upgrade -r 6.4-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

# shutdown -r now

Note that FreeBSD Update stores downloaded upgrades in /var/db/freebsd-update, so at least 400MB should be free in /var before running freebsd-update; if the /var partition is too small, the -d option to freebsd-update can be used to indicate that the upgrades should be stored in a different directory.
