I have a couple old systems that were upgraded from Red Hat 7.2 to 7.3.
The Fedora Legacy Project says they will discontinue support for Red Hat
Linux 7.3 and 9 effective December 31st of this year (2006).

I want to do one final update, but yum still thinks it's running 7.2.
Where does Yum get the $releasever variable?

# cat /proc/version
Linux version 2.4.20-28.7 (bhcompile at porky.devel.redhat.com) (gcc
version 2.96 20000731 (Red Hat Linux 7.3 2.96-126)) #1 Thu Dec 18
