[Clfs-support] i need a idea

Why can't you just define them by UUID instead of device path?

$ man mdadm.conf
$ man blkid

I couldn't find specific about mdamd.conf but its the same approach as in fstab.

Yeah, I seen the wunderbar thingy... its not exploitable on F11 with
selinux, although the author claims so.
