RAM (shmfs is a variable-sized ram disk).

I'd have to build one for atari.

Ok, the shmfs root should be built

I know some of the debian m68k buildd guys are looking at setting up 
some ataris with the CT-60. I think they've been having trouble tracking
down some parts or something. That should bring some more interest, I
should think.
