Hi guys, I can confirm this problem (now) exists on debian unstable using * 5.9.0-5-amd64 / linux-image-5.9.0-5-amd64 / 5.9.15-1 * cgroupfs-mount 1.4
It used to work until some weeks ago, but I cannot exactly pinpoint the time. I got the "Cgroup v1 clone_children flag: missing" output until I entered the mkdir + mount for /sys/fs/cgroup/systemd I could not start unprivileged containers (neither debian10 nor centos8) until I added the mkdir+mount on the "host" After adding that mkdir+mount on the Debian unstable host, I also had the same problem inside a debian9 container: I could not start docker inside a Debian 9 container until adding the mkdir+mount inside the Debian9 container. -- - Harald Welte <lafo...@gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
