[BozemanLUG] Fedora preupgrade

[David Boreham]

Touch wood, I've always been able to upgrade our Fedora machines 
in-place using yum.
In some cases the RPM database had to be fixed up afterwards (there were 
some issues
with 64-bit and 32-bit versions of the same package not living happily 
together at one time).
We've mostly switched to CentOS now, and haven't had to go through the 
upgrade
process on any of those machines yet.
