freebsd 9.1-RELEASE

The first release candidate of the 9.1-RELEASE release cycle is now
available on the FTP servers for amd64, i386, and powerpc64.  The
MD5/SHA256 checksums are at the bottom of this message.  The ISO images
and, for architectures that support it, the memory stick images are
available here:


(or any of the FreeBSD mirror sites).

Current plans are for there to be one more RC build, followed by the
release itself.  The current target schedule is here:


If you notice any problems you can report them through the normal Gnats
PR system or here on the -stable mailing list.

With both the doc and ports repositories now moved to SVN it has been
decided to not export the 9.1 release branch activity to CVS.  So
csup/cvsup update mechanisms are not available for updating to 9.1-RC1.
If you would like to use SVN the branch to use is releng/9.1.

The freebsd-update(8) utility supports binary upgrades of i386 and amd64 
systems running earlier FreeBSD releases.  Systems running 9.0-RELEASE
can upgrade as follows:

# freebsd-update upgrade -r 9.1-RC1

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 

# 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 earlier FreeBSD releases (FreeBSD 7.X, 8.X) can also use
freebsd-update to upgrade to FreeBSD 9.1-RC1, 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 7.X
or FreeBSD 8.X and FreeBSD 9.X.
