please, no, not again:
this particular horse has been beaten to death many times before.

the in kernel auto assembly should be removed for good (read the
linux-raid list archive to understand why)

it should be replaced by auto assembly in user space (mdadm), which does
not suffer from the problems that in-kernel has. neither it does suffer
from a poor configuration file like the (unmaintained) raidtools had.
and is much more cleaner and maintainable.
