<para>
Since a user can be specified both by username as well as one or
more usergroups, it is possible that several configuration lines
enable that user to create network interfaces. In such cases, any
interfaces create are counted towards the quotas of the user or group
in the order in which they appear in the file. If the quota of one
line is full, the rest will be parsed until one is found or the end of
the file.
