vol_id - probe filesystem and read label and uuid
This program is normally called from a udev rule, to provide udev with the
filesystem type of a volume and the label and uuid to name a device node.
vol_id opens the blockdevice node specified at the commandline. The following
commandline switches are supported to specify what vol_id should print:
--export export key/value pairs
--type filesystem type
--label filesystem label
--label-raw raw label
--uuid filesystem uuid
--skip-raid don't probe for raid
--probe-all find possibly conflicting signatures
--help
vol_id will only return with a non-zero exit code if the string asked for,
is not empty. All trailing whitespace will be removed, spaces replaced by
underscore and slashes ignored.
Unmangled values are available in the --export mode as hex-encoded strings
in *_ENC= keys.
