When we've got nothing to put in there don't write mdadm.conf, this means
rc.sysinit won't call "mdadm -As --run" with an empty mdadm, this is
important because:
1) It will speed up booting
2) With an empty mdadm.conf mdamd will scan all disks and try to bring
up any raidsets it can find. Including sets which we may not want to
be brought up, such as ddf metadata sets (should be handled by dmraid)
and imsm metadata sets even when nodmraid or noiswmd is specified.
