[Spice-devel] [PATCH spice-streaming-agent v3 1/5] Install udev rule

[Frediano Ziglio]

The udev rule is used to do some action when the device is added to the
system. Current rule change the permission of the special file to allow to
open it by any user.
Some systems use /lib/udev while others use /usr/lib/udev.
Allow to specify the full path to support both type of systems.
