FreeBSD The Power to Serve

FreeBSD 7.1-RELEASE Announcement

Date: January 4, 2009

The FreeBSD Release Engineering Team is pleased to announce the availability of FreeBSD 7.1-RELEASE. This is the second release from the 7-STABLE branch which improves on the functionality of FreeBSD 7.0 and introduces some new features. Some of the highlights:

  • The ULE scheduler is now the default in GENERIC kernels for amd64 and i386 architectures. The ULE scheduler significantly improves performance on multicore systems for many workloads.

  • Support for using DTrace inside the kernel has been imported from OpenSolaris. DTrace is a comprehensive dynamic tracing framework.

  • A new and much-improved NFS Lock Manager (NLM) client.

  • Boot loader changes allow, among other things, booting from USB devices and booting from GPT-labeled devices.

  • The cpuset(2) system call and cpuset(1) command have been added, providing an API for thread to CPU binding and CPU resource grouping and assignment.

  • KDE updated to 3.5.10, GNOME updated to 2.22.3.

  • DVD-sized media for the amd64 and i386 architectures

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

For more information about FreeBSD release engineering activities, please see:


FreeBSD 7.1-RELEASE is now available for the amd64, i386, ia64, pc98, powerpc, and sparc64 architectures.

FreeBSD 7.1 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 purpose of the ISO images provided as part of the release are as follows:


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

disc1, disc2, disc3, livefs, docs:

disc1 contains the base FreeBSD system and a few pre-built packages. disc2 and disc3 contain more pre-built packages. Those three can be burned to CDROM sized media and should be all you need to do a normal installation. livefs contains support for entering into a "livefs" based rescue mode but you need disc1 to do the initial boot first. docs contains the documentation.


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.

FreeBSD 7.1-RELEASE can also be purchased on CD-ROM or DVD from several vendors. One of the vendors that will be offering FreeBSD 7.1-based products is:


7.1-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 7.1-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.

More information about FreeBSD mirror sites can be found at:

For instructions on installing FreeBSD, please see Chapter 2 of The FreeBSD Handbook. It provides a complete installation walk-through for users new to FreeBSD, and can be found online at:

Updating Existing Systems

NOTE: If updating from a 7.0 or earlier system due to a change in the Vendor's drivers certain Intel NICs will now come up as igb(4) instead of em(4). We normally try to avoid changes like that in stable branches but the vendor felt it necessary in order to support the new adapters. See the UPDATING entry dated 20080811 for details. There are only 3 PCI ID's that should have their name changed from em(4) to igb(4): 0x10A78086, 0x10A98086, and 0x10D68086. You should be able to determine if your card will change names by running the command "pciconf -l", and for the line representing your NIC (should be named em on older systems, e.g. em0 or em1, etc) check the fourth column. If that says "chip="0x10a78086"" (or one of the other two IDs given above) you will have the adapter's name change.

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_7_1.

FreeBSD Update

The freebsd-update(8) utility supports binary upgrades of i386 and amd64 systems running earlier FreeBSD releases. Systems running 7.0-RELEASE, 7.1-BETA, 7.1-BETA2, 7.1-RC1, or 7.1-RC2 can upgrade as follows:

# freebsd-update upgrade -r 7.1-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

# shutdown -r now

Users of Intel network interfaces which are changing their name from "em" to "igb" should make necessary changes to configuration files BEFORE running freebsd-update, since otherwise the network interface will not be configured appropriately after rebooting for the first time.

Users of earlier FreeBSD releases (FreeBSD 6.x) can also use freebsd-update to upgrade to FreeBSD 7.1, but will be prompted to rebuild all third-party applications (e.g., anything installed from the ports tree) after the second invocation of "freebsd-update install", in order to handle differences in the system libraries between FreeBSD 6.x and FreeBSD 7.x.

The FreeBSD Security Team currently plans to support FreeBSD 7.1 until January 31st 2011. 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 7.1 including The FreeBSD Foundation, FreeBSD Systems, Hewlett-Packard, Yahoo!, Network Appliances, and Sentex Communications.
