Risk management? Is this a home network or a business network?

OK, my bad you are currently on FC2 so you've been using Fedora Core
for a while now, but no longer get updates.

I tell you support for the 2.6.9 kernel with software that has kernel
drivers is starting to get weaker and weaker. I would wait to jump to
a 2.6.18 or 2.6.20+ kernel next so your setup stays as current for
the longest time possible.

I'm talking more about personal needs vs. business. I too have been at
this a long time and know that often I will romanticize of turning my
home network into a mini version of Google...
