freebsd-update and 7.1-RELEASE-p5

[Jim Vanderveen]

I updated a fresh 7.1-RELEASE to (I thought) 7.1-RELEASE-p5 using
freebsd-update; however, uname shows me at 7.1-RELEASE-p4 after
rebooting:

$ uname -v
FreeBSD 7.1-RELEASE-p4 #0: Sun Mar 22 12:35:36 UTC 2009
root at i386-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC
$ sudo freebsd-update fetch
Password:
Looking up update.FreeBSD.org mirrors... 4 mirrors found.
Fetching metadata signature for 7.1-RELEASE from update2.FreeBSD.org... done.
Fetching metadata index... done.
Inspecting system... done.
Preparing to download files... done.

No updates needed to update system to 7.1-RELEASE-p5.
$ sudo freebsd-update install
No updates are available to install.
Run '/usr/sbin/freebsd-update fetch' first.
$

I was expecting uname to show "7.1-RELEASE-p5". Is this incorrect? Or
have I done something wrong?
