getrootdisk() {

The installation program needs to know which disk to consider
the root disk.  Note the unit number may be different than
the unit number you used in the standalone installation
program.

Available disks are:

__getrootdisk_1
	_DKDEVS=`md_get_diskdevs`
	echo	"$_DKDEVS"
	echo	""
	echo -n	"Which disk is the root disk? "
	getresp ""
	if isin $resp $_DKDEVS ; then
		ROOTDISK="$resp"
	else
		echo ""
		echo "The disk $resp does not exist."
		ROOTDISK=""
	fi
}

labelmoredisks() {
	cat << \__labelmoredisks_1

You may label the following disks:

__labelmoredisks_1
	echo "$_DKDEVS"
	echo	""
	echo -n	"Label which disk? [done] "
	getresp "done"
	case "$resp" in
		"done")
			;;

		*)
			if isin $resp $_DKDEVS ; then
				md_labeldisk $resp
			else
				echo ""
				echo "The disk $resp does not exist."
			fi
			;;
	esac
