Thanks for that!

It is a fedora 7 box which is responsible for internal dns and samba /
backup so having it set this way has been kinda handy as i have tested
the newer kernels on another similar but not as important box before
altering the default in grub.conf.

This bit of knowledge is *very* useful for me at the present time as i
have 2 CentOS 5.1 boxen (identical dell 2950s, dual quadcores, large
raid 6 yadda yadda) one of which is in production for an electronic
