 This program is normally called from a udev rule, to provide udev with the
 name, uuid or the filesystem type of a partition to name a device node.
 
 This program is normally called from a udev rule, to provide udev with the
 name, uuid or the filesystem type of a partition to name a device node.

-udev_volume_id opens the blockdevice specified by the environment variable
-DEVPATH and searches for a filesystem superblock to read the label. The
-following commandline switches are supported to specify what udev_volume_id
-should print to stdout:
-
-       no option prints all values
-  -h   prints help text
-  -l   prints the label of the partition
-  -u   prints the uuid of the partition
-  -d   read disk instead of partition
-
-If -d is specified udev_volume_id tries to read the label from the main
-block device where the partition belongs to. For now this is only useful
-for s390 dasd labels.
