I just pushed a commit adding the pre-init shell wrapper I mentioned
earlier. Seems to work fine based on a quick test in qemu.

Alternatively we could try to convince the kernel people that it makes
sense to make CONFIG_DEVTMPFS_MOUNT work with initramfs as well. It's
simple to do so (just stick a devtmpfs_mount("dev") at the bottom of
populate_rootfs), but it could potentially break existing initramfs
scripts as the mount -t devtmpfs devtmpfs /dev command will then fail.
