Although I don't really know what mount-by-label on Fedora and RHEL 
means precisely, I suspect it may not help with the _bootloader_ and/or 
with RAID device files.

Rik, do you want to have the kernel image on a SAN disk? If _not_, there 
is a solution which has long been in use with USB and FireWire disks. 
Just install an initrd along with the kernel image. In the initrd, you 
can create or rename or link to device files as you whish. Typically, 
udev is used to fetch unique persistent properties of devices and 
associate device names, symlinks, or mount points accordingly.
