he, he, did that before, it just removes the label/s

anyways, I believe that I'm now on a better track, ie:
	# gpart create -s GPT mfid0
	mfid0 created
	# gpart add -b 34 -s128 -t freebsd-boot -l r0/boot mfid0
	mfid0p1 added
	# gpart add -s2G -t freebsd-ufs -l r0/root mfid0
and now, in /dev/gpt:
	r0/boot
	r0/root

thanks Stephan and Andrey,
