Getting a kernel with full filesystem support into a 32K rom would be hard.
With a larger ROM such a system would be possible. I belive some network
cards can take up to 128K of EPROM. ROMfs does not currently work, but I
have every intention of fixing it. One of the advantages of the idea is
that it is not actually necessary to copy the code segment into RAM. In can
just run in place on the ROM providing the data segment is copied into
RAM.
