Comment # 9 on bug 1205636 from Michael Andres

On my TW
 $ cat /proc/592/cgroup 
 0::/system.slice/systemd-udevd.service

On 15.x e.g
 # cat /proc/493/cgroup
 12:devices:/system.slice/systemd-udevd.service
 11:perf_event:/
 10:hugetlb:/
 9:rdma:/
 8:blkio:/system.slice/systemd-udevd.service
 7:freezer:/
 6:cpuset:/
 5:pids:/system.slice/systemd-udevd.service
 4:net_cls,net_prio:/
 3:cpu,cpuacct:/system.slice/systemd-udevd.service
 2:memory:/system.slice/systemd-udevd.service
 1:name=systemd:/system.slice/systemd-udevd.service
 0::/system.slice/systemd-udevd.service

On both the service would be detected as 'systemd-udevd'.


If someone can still reproduce it, please attach the output of the content of
/proc/PID/cgroup for the command thet should have a service associated.
