booting a diskless amiga with netbsd?

[Joerg Kollmann <joergk%informatik.uni-bremen.de@localhost>]

I want to boot a diskless amiga (ie loading the boot program from
floppy) using my a3k/netbsd1.3 as bootp/nfs/(whatever) server. Is there
any boot program to do this? If not, is there any example code I could
use to write such a program?  Which changes are needed for the kernel
to nfs-mount the root partition?
btw: if I want to boot a diskless intel pc (to netbsd/i386), are the
required kernel changes the same?
