+ <listitem><para>Allows the container
+ to share certain system facilities
+ with the host. More specifically, this
+ turns off PID namespacing, UTS
+ namespacing and IPC namespacing, and
+ thus allows the guest to see and
+ interact more easily with processes
+ outside of the container. Note that
+ using this option makes it impossible
+ to start up a full Operating System in the
+ container, as an init system cannot
+ operate in this mode. It is only
+ useful to run specific programs or
+ applications this way, without
+ involving an init
+ system in the container.</para></listitem>
