[dm-devel] [PATCH 25/78] multipath.rules: fixup race condition with systemd

[Hannes Reinecke]

systemd will call 'fsck' on any device, even if no device
type is found. This might cause a race between the mount call
and any fsck call on the device-mapper device.
So for multipath we should arbitrary set the device type to
'none', as then systemd with detect a missing 'fsck.none'
command and skip fsck here.
