[dm-devel] [PATCH 26/78] 11-dm-mpath.rules: Import blkid values if all paths are down

[Hannes Reinecke]

When all paths are failed we should not try to run any programs
requiring disk access. However, we still need to create the
symlinks so as not to confuse systemd.
So import the blkid values from the database in these cases.
