Not sure if you were following my logic completely; MILO would actually
contain the md driver, just as it contains almost-verbatim copies
of several other Linux kernel drivers. The drive info md needs for
booting would be passed on the kernel command line.
Without flashROM and MILO, booting RAID becomes a lot more difficult. :)
Re-creating stripes does look nasty, though :) I am looking at the
RAID patches now... (and wondering if md RAID5 can beat Solaris ODS)
