First issue is: what would it take to squeeze any useful combination of kernel, init plus two-three (small) user programs in 4MB? Which (dispensable) parts of the kernel require so much space? After removing all I could think of (leaving FFS, fd0, and ed0, though) the kernel size is still about 700kB big, and quite another question is how this translates into running size... The second issue is this: currently we're unable to boot (using BIOS) and mount as / other filesystems than FFS, NFS and CD9660. It would be great if we could use MSDOSFS as well (using special version of biosboot, with FAT support compiled-in instead of FFS). Device nodes would be on DEVFS. What for? This could help get rid of fbsdboot.exe and related troubles - we could just directly start and run (and install!) on MSDOS partition.
