-The value
-.I $local
-can be used instead of a specific username. In that case, udev will determine

-example, to let hot-plugged devices, such as cameras, be owned by the user at
-the current console. Note that if no user is currently logged in, or if udev
-otherwise fails to determine a current user, the
-.I default_owner
-value is used in lieu.
