Subject: [PATCH] - If run under sudo, allow user to delete the built RPM -
 Stop vcached, delete the old reference image, and empty the cache   before
 installing a new version; restart vcached after installing - make sure
 /vservers is mode 0000 - make sure the reference image has an /etc/planetlab
 directory before   trying to install in it
