I didn't think this was possible at all!

What brand, model, chipset is that?
How much disk and memory has it got?

No, sorry. 

I'm guessing its easier creating application specific
persistence, since an application knows exactly where
to cut corners, implementing just enough persistence.

Of course, if it's for more than a few select apps,
eventually it would be worthwhile to do it system-level,
but I'm sure its a challenge, doing both kernel-side
and userland persistence and keeping these in sync,
considering volatile resources like open file descriptors
and network sockets.
