Sounds like you want a tmpfs, possibly union mounted over the
"stable" filesystem, with "rsync" being your :sync" command.

Sounds like you're looking for a combo of overlay mounts on top of tmpfs
- the flush to disk you'd have to manage manually but I've done this
with some success in the past and I do seem to recall it being discussed
to provide pseudo read-write over a read-only medium such as a CDROM
I know NetBSD supports RAM disks. I also know it uses them for
installation, but I'm not sure if they are overlays on top of the static
disk images or if they get loaded/populated with the image after the
system boots. The effect is the same, either way. You end up with a
writable file
