>Description:
	This patch add the ability to create FAT32 partition (only on MBR scheme) while here I added the ability to create linux, linux-swap and linux-lvm partitions
	
	gpart add -t win95-fat32 da0 to to do it
	
	I can't test on current but it seems to be the same files as on 8-stable, so the patch should also work on current
