In order to make use of version 1.0 superblocks in md raid arrays, the system
boot up process must be able to work without raid autorun capabilities. Right
now, the section of rc.sysinit that calls mdadm won't work, but it's hidden by
raid autorun doing the work for it. Due to lack of devices in the /dev
filesystem, the raid bringup via mdadm needs to read as mdadm -A -s --auto=yes
(or else we have to change anaconda to add an --auto= flag to each ARRAY entry
in /etc/mdadm.conf, which might be preferable, but for the sake of safety, that
should override the command line, not cause us to leave the --auto part out of
the command line).
Added in CVS, will show up in rawhide eventually.
This was fixed in 8.47-1.
