-udev_volume_id - partition, filesystem, disklabel reader
+vol_id - partition, filesystem, disklabel reader
 
 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.
-
-udev_volume_id will only return successful if the string asked for, is not

 empty. All trailing whitespace will be removed, spaces replaced by underscore
 and slashes ignored.

 The following rule will create a symlink named with the label string:
-  KERNEL="[hs]d*", PROGRAM="/sbin/udev_volume_id -l", SYMLINK="%c"
+  KERNEL=="[hs]d*", PROGRAM=="/sbin/vol_id -l %N", SYMLINK+="%c"

 ignored.
 
 To give it a try, you may call it on the commandline:
