<description>
|
||
<p>lxc-user-nic when asked to delete a network interface will
|
||
unconditionally open a user provided path. This code path may be used by
|
||
an unprivileged user to check for the existence of a path which they
|
||
wouldn’t otherwise be able to reach.

|
||
including special device files.
