FreeBSD 7.2RC Released

The second of two planned Release Candidates for the FreeBSD 7.2-RELEASE cycle is now available. ISO images for Tier-1 architectures are now available on most of the FreeBSD mirror sites.

The freebsd-update(8) utility supports binary upgrades of i386 and amd64
systems running earlier FreeBSD releases. Systems running 7.0-RELEASE,
7.1-RELEASE, 7.2-BETA1, or 7.2-RC1 can upgrade as follows:

# freebsd-update upgrade -r 7.2-RC2

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
