Michal Schmidt a96e4839d5 rules: avoid mounting raid devices too early
/dev/md0 appears as soon as the first component of the raid array is
added by incremental assembly rules. This is too early for systemd to
attempt to mount the device. The device should be considered plugged
after the raid array becomes active.
