What are you installing on FC5 via yum anymore?

Finding a working (and trust-able) FC5 repo at this point may be a trick, 
google has been my friend in the past when needing some really old FC stuff.
If you find one, I suggest (if we can't convince you to upgrade to SOMETHING 
that is secure) don't add that to your yum.repos.d files, but mirror it 
(rsync|wget) to local media.

rsync|wget
once you have it change the yum.repos.d files so that mirrorlist is commented 
and use
baseurl=file:///path/to/my/mirror/fedora/linux/core/$releasever/$basearch/[os|updates]/

change all the yum.repos.d files enabled=1 to enabled=0 [This is probably the 
best place to start for you anyway seeing as you will likely not need anything 
more from the base and updates repositories on those machines anyway.]


start planning the upgrade ... and put those machines behind a firewall that 
does not allow them to see anything called the internet, i.e., air gap them 
with a real air gap.

If you have to have something that is nearly that old in production, may we 
suggest looking at RHEL 5.2 or Centos?  If you need something that will be 
supported for more than 13 months in the future, may we suggest looking at 
RHEL 5.2 or Centos?
