I am currently playing with unionfs-fuse and archiso, so no need for
extra modules.

Two issues:
1) There is no "append" feature like with aufs, so all branchs should be
mounted in one step.
2) Since is an userspace solution and there is no support for "omit_pid"
[#1] in initscripts at the time, shutdown and reboot fails.

Notes:
1) I never used it so I do not know how stable is.
2) No patches at this moment I just experimenting from ramfs# command line.
