ro: Inject overlayfs, using DATADEV '/data' partition as 'upper'; Disable rootfs resize @ init (1st boot)
/etc/fstab didn't work to mount the overlayfs (boot freeze due to some dependencies).
Hence we use our own 'overlay_mount.service' Before 'local_fs.target',
which mounts '/data' and its overlays.
We also disable rootfs resize @ init (1st boot),
since the rootfs is immutable from here on.
