================================================================
  
      * this method is racy. post-start is running in parallel to init process inside of guest system. If guest is faster and tries to configure networking before post-start puts new iterface into guest you are doomed. Fortunately this is unlikely to happen as post-start is short and should always be first before networking is being configured by guest scripts. Race could be avoided by implementing proper netns interface moving support into util-vserver scripts.
  
-     * enabling pid namespace is likely to break post-start script (part with guest pid fetching for iproute2 netns use)
+     * enabling pid namespace is likely to break post-start script (part with guest pid fetching for iproute2 netns use). Using vps (aka context 1 spectacor mode) to find guest process pid but in host namespace is likely to solve this problem.
