Bugfixes.
The program vol_id is removed from the repository and blkid from the
latest util-linux-ng package replaces it. Persisten disk links for
label and uuid depend on the util-linux-ng version of blkid now. Older
versions can not be used with udev.
The program vol_id and the library libvolume_id is removed from the
repository. Libvolume_id is merged with libblkid from the util-linux-ng
package. Persistent disk links for label and uuid depend on the
util-linux-ng version (2.15) of blkid now. Older versions of blkid
can not be used with udev.
Libudev allows to subscribe to udev events. To prevent unwanted messages
to be delivered, and waking up the subscribing process, a filter can be
