Package: grub
Version: 0.97-46
Severity: normal
update-grub writes to /boot/grub on /dev/sda instead of /dev/md0
(/dev/md/0). This is bad because then the system doesn't boot because
the RAID arrays don't start.

update-grub writes to /boot/grub yes. But to the _mounted_ one.
If you mount /dev/sda1 as /boot then of course only sda1 is changed.
If you mount /dev/md0 as /boot then md0 get's changed.
If your RAID doestn't start anymore then it's your own fault, not GRUB's
If the kernel thinks the RAID isn't fully synced it should just start a
resync and maybe some changes then gets lost.
Or do you talk about `savedefault' feature?
Well GRUB changes only that little small number in
the /boot/grub/default file.
grub-legacy doestn't support RAID at all so it only gets changed on one
disk.
But this isn't a real problem, the filesystem (i.e. metadata) doestn't
get changed at all, for example the filesize of it will never change.
grub2 supports Linux Software RAID just not yet that `savedefault'
thing.
