nothing that i'm aware of -- i've never put these devices into fstab. i
disabled smartsuite because it was holding /dev/hdN open, but that didn't
change anything.
i just tried a "linux init=/bin/sh" boot, and it's still saying Device or
resource busy:
init-2.05a# raidstop /dev/md0
md: md0 still in use.
/dev/md0: Device or resource busy
init-2.05a# mount /proc
init-2.05a# cat /proc/mdstat
