>Description:
	During installation, the sysinst program (in the amd64 port)
	insists to create an MBR even when installing on a RAID device.
	Of course, this makes all the partitions move 63 blocks.
	As this includes the root partition, the boot will fail.
>How-To-Repeat:
	Install NetBSD 4.0_BETA2/amd64 on a RAIDFRAME raid device.
>Fix:
	Add "raid" with the "no_mbr" modifier in
	distrib/utils/sysinst/arch/amd64/md.h
	as in the following patch:
