I had a question related to kernel configuring and stuff. Since the
topic has come up here, I'll chime in.

I want to run Xen on Fedora Core 6. The default Xen kernel in Fedora
comes PAE enabled, but I don't want that and so have to disable it.
I've figured how to recompile my own kernel based on Fedora's kernel
but with PAE disabled (following the instructions at this link:
http://felipe-alfaro.org/blog/2007/02/04/netbsd-31-under-xen-303/).
What concerns me, however, is that its quite possible in the near
future an updated kernel is released by Fedora and that would
over-write my default kernel. So I'd like to know what steps I can
take to prevent this ...

Is it possible I can tell Fedora not to update my kernel, but instead
inform me of the availability of a newer one so I can compile one from
source.

Is it possible I can set some option somewhere so Fedora automatically
compiles newer kernels for me with PAE disabled?
