Sun 07 Dec 2014 11:13:46 AM UTC, comment #2: My main concern is that by default mdadm allows IMSM only on hardware that supports it, so we are reasonably sure that it can be considered available at boot time. But DDF can be created as pure software array, which cannot be used as boot device in this case. So the actual question is not IMSM or DDF, but "is it hardware supported array or not". |

We don't currently have DDF drivers, so assuming that DDF is fakeraid is the only way to install. But we can warn about the need of DDF fakeraid BIOS support.
