Upgrading from FreeBSD 8.1 to FreeBSD 8.2

Took the giant leap from 8.1 to 8.2 this evening.

Simple as 1,2,3,4.

# freebsd-update upgrade -r 8.2-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:

# freebsd-update install
At this point, users of systems being upgraded from FreeBSD 7.4-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 8.2-RELEASE:

# shutdown -r now
