Hi, I just updated to F30 and my docker setup with user namespaces doesn't work anymore. When I try to run: docker run -it --rm docker.io/php:7-fpm-alpine sh I get this error: docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "process_linux.go:402: container init caused \"rootfs_linux.go:58: mounting \\\"mqueue\\\" to rootfs \\\"/var/lib/docker/1000.1001/btrfs/subvolumes/38ce5c87e31bbbcec010db85 383d1af57e8652ff4e4c411cebe0c2102a36a020\\\" at \\\"/dev/mqueue\\\" caused \\\"operation not permitted\\\"\"": unknown.
I tried to disable SELinux with setenforce 0 but got the same result. However, dk run --userns=host -it --rm docker.io/php:7-fpm-alpine sh works fine. So it seems to be limited to user namespaces. My kernel: 5.0.9-301.fc30.x86_64 Any ideas on where this may come from? This worked fine on F29 (and probably on older versions too, I have this setup for a while now).
