Thanks. Will try it in the next few days. Will also install grub to the
MBR of all my disks, so whichever gets picked at boot time will work.
Is there an eaasy way to do this, so that they'll all get updated as
necessary when aptitude installs a new kernel? Or it this not something
that the MBR cares about?
And is th association of, say, /dev/sdb with a particular hard drive
consistent if there's no change in hardware, or does it depend on random
boot-tine timing issues?
