udev 142
====
Bugfixes.

The program vol_id and the library libvolume_id are 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
installed, to drop messages inside a kernel socket filter. The filters
match on the <subsytem>:<devtype> properties of the device.
    This is part of the ongoing effort to replace HAL, and switch current
users over to directly use libudev.
    Libudev is still marked as experimental, and its interface might
eventually change if needed, but no major changes of the currently exported
interface are expected anymore, and a first stable release should happen
soon.

A too old kernel (2.6.21) or a kernel with CONFIG_SYSFS_DEPRECATED
is not supported since while and udevd will log an error message at
startup. It should still be able to boot-up, but advanced rules and system
services which depend on the information not available in the old sysfs
format will fail to work correctly.

DVB device naming is supplied by the kernel now. In case older kernels
need to be supported, the old shell script should be added to a compat
rules file.
