FreeBSD-update?

[Walter Hurry]

When I issue 'freebsd-update fetch install I see this:
----------------------------------------
Looking up update.FreeBSD.org mirrors... 3 mirrors found.
Fetching metadata signature for 9.1-RELEASE from update5.freebsd.org... 
done.
Fetching metadata index... done.
Inspecting system... done.
Preparing to download files... done.

No updates needed to update system to 9.1-RELEASE-p2.
No updates are available to install.
----------------------------------------
So if 'No updates (are) needed to update system to 9.1-RELEASE-p2',
how do I actually update to 9.1-RELEASE-p2?

$ uname -r
9.1-RELEASE
