[systemd-devel] [PATCH] rules: add by-parttypeuuid rule for GPT labeled partitions

[Sage Weil]

The Ceph OSD initialization relies on identifying GPT partitions by type
in order to mount data volumes and start daemons.  Currently we ship this
rule separately, but it is awkward to duplicate the conditional logic that
precedes this block and it would be much simpler if it were simply included
in the upstream rules.
