But such an implementation doesn't exist yet.
As first step we could split the raid autoconfig code from the raidframe code
itself. This would allow to have raidframe devices attached via different
autoconfig methods (ataraid, raidframe-style labels on disk, etc ...).
Then it would allow different raid softwares to be used by these autoconfig
options ...
