The only problem with "rolling your own" is that when there is a kernel
update, or more importantly, a security fix, you then have to go back
through the build for each machine again. I only build special kernel's
when I have something that needs to work at max efficiency. That is NOT
the way to go for a bunch of servers. The tradeoff between kernel
efficiency and update efficiency is not worth it.

The only time it is worthwhile to "roll your own" is when you have a need
for something other than the lame 2.6.8 kernel, or when you have a machine
that will be running 99% of its resources and you want to give it one or
two percent more to play with.
