=item B<--name=>I<name>

When this parameter is used, B<dh_installudev> looks for and

debian/I<package>.udev.

Sets the priority the file. Default is 60.

Note that this command is not idempotent. L<dh_prep(1)> should be called
between invocations of this command. Otherwise, it may cause multiple
instances of the same text to be added to maintainer scripts.
