Yay! A solution for the kernel 'improvements' and the udev virus! Have
to do it by hand, it sounds like, but maybe it'll work.

Disk controller software used to call SCSI drives sda... and the IDE's
hda... When I set the SCSI ID to 0 on my system (boot) disk, it'd be
called sda -- all the time -- and grub's menu.lst and fstab would never
have a problem. When I bent something, I could at least boot the system
and fix it.

Then somebody had the brilliant idea of calling everything sd... Now
whatever is scanned first, SCSI, IDE, SATA, USB sticks, whatever, gets
called sda. Very poor.

udev was supposed to fix this, I think. But the installer(s) don't build
the rules, so when I installed Heron on my Mac Pro the other day, then
turned on an external SCSI disk, then updated Ubuntu's kernel, I got to
reinstall Ubuntu.

It looks like Ubuntu's got fstab fixed and menu.lst sorta fixed (it
still refers to the BIOS' (hd0,1) -- don't know, but that may be a
problem with grub). Getting there...
