After preupgrade, system is still f15
I went through the preupgrade procedure to get from fc15 to fc16, but the system still seems to think it is fc15:
> cat /etc/redhat-release
Fedora release 15 (Lovelock)
> cat /proc/version
Linux version 188.8.131.52-1.fc15.x86_64 (firstname.lastname@example.org) (gcc version 4.6.1 20110908 (Red Hat 4.6.1-9) (GCC) ) #1 SMP Tue Mar 20 16:30:08 UTC 2012
Any idea what I'm doing wrong?
