+ <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.
