Have a look at unionfs (debian packages unionfs-fuse, mhddfs and aufs.
All of these are different implementations of the same concept). These
should allow you to have one filesystem as read-only, and another as
read-write, so that reads are taken from the RO filesystem and writes
are sent to the RW filesystem (copy-on-write).

Not used them myself, but they should be documented well enough.
