I don't know anything about ramfs but maybe you can modify it to read all disk from storage then write back when done? Sounds really inefficient though. Maybe if it was done with system files it'd be more practical. AFAIK, but a bit off topic, DamnSmallLinux can do this. Maybe you'd like to check that out.
