At http://www.freebsd.org/handbook/backup-programs.html, there is a
script for creating a bootable floppy. Part of this script is the MINI
kernel. The example is out of date and doesn't work under 4.2.
I've included my amended mini-kernel when trying to convert it to 4.2-
stable. But it fails to compile (the error is at the end of this message).
Given the increase in kernel size since this document was created, is it
still possible to create a single floppy kernel + tools which is bootable?
If so, could someone please advise me on how to correct the error
below. If not, I'll submit a patch removing this section from the
handbook.
thanks.
