Re: alpha 5.0 BOOTMFS way too fat ..

Only after throwing out valuable things like nearly all drivers
(including ahc, mlx, tga), INET6, NFSCLINET can I get a kernel which
fits:

% ls -l kernel.gz
-rwxr-xr-x  1 gallatin  wheel  1223511 Oct 27 17:10 kernel.gz*
  

I've appended a patch against the BOOTMFS that make release
currently generates.

Are there any binutils options to make things smaller which we're not
currently using?

Maybe we need to go to a three-floppy install? (loader on first
floppy, kernel on second, drivers on third)
