The same question came to my mind.
But I think what you need is 'mount --move' before switch_root.
See also CVS_TREE/aufs/sample/diskless/linuxrc.
When you use aufs as a root filesystem, you need to pay attention at
shutdown. Generally the shutdown script remount the root filesystem as
readonly because it cannot be unmounted.
In aufs world, you also need to remount your writable branch filesystem
as readonly, in order to flush/write-back to the branch.
(from the aufs manual)
----------------------------------------------------------------------
When your aufs is the root directory of your system, and your system
tells you some of the filesystem were not unmounted cleanly, try these
procedure when you shutdown your system.
.nf
# mount -no remount,ro /
# for i in $writable_branches
# do mount -no remount,ro $i
# done
.fi
If your xino file is on a hard drive, you also need to specify
`noxino' option or `xino=/your/tmpfs/xino' at remounting root
directory.
