* The dmraid user-space has not changed and does still depend on
the dm-raid45 module.
* For Intel fakeraid BIOSes mdadm gained ability to parse IMSM
meta-data and set up md RAID using raid456. But this is not
tested (and might not be the target setup right now).
* Also I have no data about support for other fakeraid variations.
Testing with IMSM fakeRAID:
* The installer currently creates md raid volumes even before
asking to enable then or not. This seems to be a bug
(lp 1008423).
* Due to above, no matter what the answer is, the installer
tries to look at volumes contained in the RAID while the
RAID volume is still read-only (lp 1008479).
Recommendation:
Keep dm-raid45 active for this cycle.
