Re: boot-floppies: how do I go about making my own version
Its over a day, and there are not takers for your
query .. Offering an incomplete suggestion to keep
this thread alive.
I am attaching my boot-floppy making script below.
Its just a barebone script, merely booting into
your existing system. Does NOT have the additional
features that you are looking for. Could serve as
a starting point for further development.
This csh script was taken from my SCO based sysop
a couple of years ago, and I just added few things
to it like formatting etc. I'm on bash and don't
know enough csh to extend this. Your requirement
of placing a kernel of your choice is met here.
You need to add more to it for network config and
ftp installs. There would be limited free space on
the disk for experimentation, depending upon the
size of your installed kernel.
Perhaps others can throw in their bit from here.
Any joy from the debian-boot mail list ?
