nope

most everything under /var/log /var/spool /var/run /var/tmp
lots of whacky stuff to turn off that uses /proc, /tmp
.. gazillion ittty-bitty files ...
just look at knoppix as what is symlink to memory
or turn off that feature or any other cdrom based distro that works
properly .. ( most don't .. ie.. i want a cd distro that allows
the cd to be popped out so that other apps can be loaded )

memory is cheap compared to file-by-file analysis of what needs
to be writeable or not is gonna take more $$$ and time than
the memory
and if things are meant to be kept small ..
boot off 8MB compact flash or floppy and have everything
running on it or in (precious) memory
have fun
