-Subject: [PATCH] Start device units for uninitialised encrypted devices
-
-This is necessary because the NixOS service that initialises the
-filesystem depends on the appearance of the device unit.  Also, this
-makes more sense to me: the device is ready; it's the filesystem
-that's not, but taking care of that is the responsibility of the mount
-unit.  (However, this ignores the fsck unit, so it's not perfect...)
