Why do you call this weird? Is it not possible to use BOOTP to just
get an IP address assigned?
What method for network configuration do you suggest for a minimized
embedded system? Including tools like ifconfig and set-up scripts to
call them?
I've been using similar combinations (RARP + initrd) for some time
without problems; would this fail using BOOTP?
Ummm... let's see:
Using RARP:

This works for me, too.
