poky script ./meta/recipes-core/udev/udev-extraconf/mount.sh is called
by systemd-udev rules every time a storage device is found, and it is
responisble to automount them. The init script waits until the device is
automounted to finish the boot process.
The mount.sh script sues "stat", and right now our busybox doesn't have
it enabled. As a result, stat is not found, the script fails, the
device is not mounted, and the init script hangs forever.
