# * rescue floppy: rescue-new.bin
# * root floppy: root-new.bin
# * driver floppies: drivers-new-n.bin
#
# expects:
# * enough free diskspace to compile kernel and build floppies
# * ./linux must be the kernel src directory (or a symlink to it)
# * the kernel src should be configured before you start this script
#   if there is no .config in the kernel src directory, but in the current
#   dir, then this will be copied there
