You can look at the process described in src/distrib/i386/floppies which
first builds a kernel with a ramdisk (md), a filesystem image (ramdisk-*),
and then frobs the ramdisk into the kernel's reserved space using
mdsetimage(8), resulting in a kernel that can be bootet and that has the
ramdisk image included.

The process itself is scattered across a bunch of machine-dependent and
machine-independent Makefile-fragments, see src/distrib/common and
src/distrib/i386/floppies/common etc.

I didn't write any of these, but I've used them myself in the g4u project
to make a custom floppy (see .sig :-).

I guess an "embedded howto" would be a nice addition for our online docs
at or the NetBSD Guide at
