Here's an init script that works for me on a server that has its root
partition on a software raid5 on /dev/md1. It uses busybox for all
commands except mdadm.

	#! /bin/sh
	export PATH=3D/bin:/sbin
	echo initramfs startup

	cat > /etc/fstab << EOF
	proc /proc proc defaults 0 0
	sysfs /sys sysfs rw 0 0
	EOF

	cat > /etc/mdev.conf << EOF
	null 0:0 666
	ptmx 0:0 666
	EOF

	mount /proc
	mount /sys
	mdev -s
	mknod /dev/md1 b 9 1
	echo 'DEVICE partitions' > /etc/mdadm/mdadm.conf
	mdadm -E --scan >> /etc/mdadm/mdadm.conf
	mdadm -A --scan || sh
	mount -oro /dev/md1 /mnt || sh
	mount --move /proc /mnt/proc
	mount --move /sys /mnt/sys
	cd /mnt
	mount --move . /
	exec chroot . /sbin/init 2 > /dev/console 2>/dev/console < /dev/console
