Is it legal to reference /dev/hdXX when RAID has been enabled?
I don't know I really like this...
As an extreme example, consider the serious problems that could occur
if the kernel is busy syncing /dev/md2 (/dev/hda1 and /dev/hdc1),
while using /dev/hda1 (non-RAID) as the root file system.
Then again, I guess installation could set the partition type
to non-RAID, so RAID support will never get enabled unless
the administrator enables it.
I don't see any problems installing a RAID partition by default if
RAID is not enabled by default.
Comments?
