I do not use raidctl -i after an unclean reboot, and have not yet seen
any problems. I was reading the code before going on holiday to see
what rebuild parity does - but while I may know a bit about the layout
and operation of RAIDframe, I am still a touch hazy about RAID
algorithms in general. More reading required.

One thing that I haven't been able to check one way or the other is if
/etc/rc.shutdown gets run before or *after* partitions are unmounted.
If after, then we could run 'raidctl -u /etc/raid...' before shutdown.
If /sbin/raidctl is still available that is.

Yes, some kernel messages come up saying that the component was not
clean.

Running around like a headless chicken here, so if you get anywhere,
please share...
