LXC development for Precise

Registered by Serge Hallyn

Several items should be worked on during this cycle:

   provide a default bridge and lxc.conf
   proper reboot
   containerized syslog
   userns vfs
   apparmor support
   ARM support
   tests in qa-regression-tests
   allow mknod in the container by default (and potential udev problems)
   Update mountall to not require our current /lib/init/fstab hack
