Docker is not working on R4S

[weikai]

Is docker working in the latest build? I got the following error message from dockerd on R4S.

I didn't test it, just added the Openwrt packages, so there might be missing kernel options or missing packages, but those logs don't give a clue. I will try to find what's wrong when I get a bit of spare time.

Added kernel config options found here : https://gitlab.com/mcbridematt/openwrt-container-feed/-/blob/master/openwrt_configs/openwrt-docker-host-config-x86_64

Hope it helps
