<para>A space-separated list of policies by which the interface's alternative names
|
||||
should be set. Each of the policies may fail, and all successful policies are used. The
|
||||
available policies are <literal>database</literal>, <literal>onboard</literal>,
|
||||
<literal>slot</literal>, <literal>path</literal>, and <literal>mac</literal>. If the
|
||||
kernel does not support the alternative names, then this setting will be ignored.
