namespaces +are used, and the bind mount is followed by the cgroup mount in the +spec, the cgroup is mounted using the bind mount's mount fd. + +This can be reproduced with podman 4.1 (when configured to use runc): + +$ podman run --uidmap 0:100:10000 quay.io/libpod/testimage:20210610 mount +Error: /home/kir/git/runc/runc: runc create failed: unable to start container process: error during

found earlier since it requires using userns, and even then +mount fd is ignored by mountToRootfs, except for bind mounts, and all the bind +mounts have mountfd set, except for the case of cgroup v1's /sys/fs/cgroup +which is internally transformed into a bunch of bind mounts. + +This is a minimal fix for the issue, suitable for backporting. + +Fixes: 9c444070ec7 ("Open bind mount sources from the
