@rickicode script seems unable to download OpenWRT image:

Maybe just missing something like wget $BD_URL/rootfs.tar.xz -O /var/lib/vz/template/cache/OpenWrt-$VER.tar.xz?

I created a new script that downloads the current, or snapshot from OpenWrt directly, and it allows you to specify all the options as prompts. Including the Interface/bridge for WAN, and LAN, Autodetect next available container ID, and even specify what IPv4 subnet you want to use. If you want to install the Snapshot version, it will even prompt you if you want it to auto install LuCi.
