If each of those subdirs is also empty then you can rmdir them, then rmdir /cgroup/arch64-1. Or, use a release agent, which is what I do. cat << EOF > /bin/remove_dead_cgroup.sh #!/bin/sh echo "Removing dead cgroup .$*." >> /var/log/cgroup rmdir /cgroup/$* >> /var/log/cgroup 2>&1 echo "return value was $?" >> /var/log/cgroup EOF echo /bin/remove_dead_cgroup.sh > /cgroup/release_agent echo 1 > /cgroup/notify_on_release > $ sudo ls -lRaFZ /cgroup/arch64-1 > /cgroup/arch64-1: > total 0 > drwxr-xr-x 6 root root ?
