specified, the container shares its root file system
with the host.

<para>
For directory or simple block-device backed containers,
a pathname can be used. If the rootfs is backed by a nbd
device, then <filename>nbd:file:1</filename> specifies that
<filename>file</filename> should be attached to a nbd device,
and partition 1 should be mounted as the rootfs.
<filename>nbd:file</filename> specifies that the nbd device
itself should be mounted. <filename>overlayfs:/lower:/upper</filename>
specifies that the rootfs should be an overlay with <filename>/upper</filename>
being mounted read-write over a read-only mount of <filename>/lower</filename>.
<filename>aufs:/lower:/upper</filename> does the same using aufs in place
of overlayfs. <filename>loop:/file</filename> tells lxc to attach
<filename>/file</filename> to a loop device and mount the loop device.
