RAID/LVM Root Filesystem on SuSE8.2

[Mike Reinehr]

Just a quick question. Booting from a RAID 1 device seems to work easily, but 
would it work from RAID 0, RAID 5, or RAID 10, as well? Personally, I suspect 
that  it works only with RAID 1 because GRUB (or LILO, I suppose) still can 
access the component drives individually and that striped drives would not 
work. (Sorry, I haven't had time to experiment, myself.)

Thanks!
