yum rollback?

[Chris Strzelczyk]

Hello everybody,

I was wondering if there is a way to roll back yum packages.  I was 
reading about up2date which
has a repackage and rollback option which will seem to work for me 
however, I would like to continue
using yum.

Also,

I am fairly new to security on Linux.  What are the main pros/cons of 
yum vs. up2date.  Are they that
much different.

Thank you all in advance.
