I don't see what's bad in mounting a RAID degraded.  Yeah, it provides no
redundancy but that's no worse than using a single disk from the start.
And most people not doing storage/server farm don't have a stack of spare
disks at hand, so getting a replacement might take a while.

Being able to continue to run when a disk fails is the whole point of RAID
-- despite what some folks think, RAIDs are not for backups but for uptime.
And if your uptime goes to hell because the moment a disk fails you need to
drop everything and replace the disk immediately, why would you use RAID?

Is there a more recent version somewhere?  Mechanically rebasing+resolving
conflicts doesn't work, I'd need to do a more involved refresh, which would
be a waste of time if it's already done by someone with an actual clue about
this code.
