+Subject: [PATCH 1/1] Detail: fix --detail --export for uuid_zero
+
+Mentioned commit (see Fixes) causes that devices with UUID
+equal to uuid_zero was not recognized properly. For few devices
+the first one was taken always, and the same information was
+printed. It caused regression, when few containers were created,
+symlinks were generated only for the first one.
+
+Add checking if uuid is uuid_zero and, if yes, use devname to
+differentiate devices.
+
+Fixes: 60c19530dd7c ("Detail: remove duplicated code")
