It's SquashFS with LZMA compression plus AUFS (UnionFS redesigned from scratch).
http://en.wikipedia.org/wiki/UnionFS

The read-only filesystems are in fact .lzm files which are mounted as
loop-device. As a matter of fact the filesystem where they really
reside doesn't matter much.
I won't give you further information though because, as I'm not fond
of the idea of making a ro filesystem writable, I've not spent much
time on the topic and therefore can't be sure to properly answer.
