 I hacked together the following shell script to build my own
boot floppy with my own kernel in it...  It works for 2.1.6, and
assumes that you initially did a "clean" install because it grabs
the /stand directory that was previously installed (so you don't
have to remake all that stuff.)

 Just change the "rd" variable to wherever you'd like your release
to be (it's set to /usr/tmp/release).  After the script completes,
you'll find $rd/floppies/boot.flp. [p.s. run the script as "root".]
