HiI've come across mini_fo for embedded devices. It overlays a r/w
over a r/o one. You might be able to script the system to commit changed
(and not the deleted) from the mini_fo storage to the r/o partition somehow.
think it would be an even more ugly hack
than your idea tho, and there would
be a risk of filename collisions.
chattr no good, no?
