GENERIC _is_ the old kernel.  That's why it's recommended
never to edit GENERIC, but to always copy it to a new
config file.

Again, it won't hurt anything to back it up ... you can
never have too many backups.

NP.  I just wanted to bring it up in case.  It's a
fairly common mistake to update ones sources, build a
new kernel without rebuilding world, and then wonder
where all the problems are coming from ;)
