BYLD is a little package that helps you to build a Linux distribution on a
single floppy disk to use as you want (net client, rescue disk...).
This is
not a complete distribution: it was made only to build a (mini)distribution
on a floppy/cdrom.
BYLD 1.x is now without support! I'm working about BYLD 2 (planning state) and any help is welcome.
