Indeed.  I just tried to build the atari port with Lua enabled, it
failes because of teh size.  So for now we could turn off Lua for these
ports, but we run into a big problem if sysinst one day requires Lua.
So I think it is better to try to shrink sysinst already now, so that it
still fits on the install floppy.
