Starting code-server container with userns-remap fails

[thbley]

Since I'm using userns-remap in docker daemon, I have to use userns=host to be able to write files inside a docker container with my host uid. Starting code-server using userns=host fails.

Expected Behavior

docker container starts

Current Behavior

docker run --rm -it --userns=host linuxserver/code-server:latest bash gives: s6-overlay-preinit: fatal: unable to chown /var/run/s6: Operation not permitted

Steps to Reproduce

/etc/docker/daemon.json {"userns-remap": "dockremap", "icc": false,"experimental": true} /etc/subuid dockremap:231072:65536 /etc/subgid dockremap:231072:65536

docker run --rm -it --userns=host linuxserver/code-server:latest bash gives: s6-overlay-preinit: fatal: unable to chown /var/run/s6: Operation not permitted

docker -v Docker version 19.03.13, build 4484c46d9d
