Apparently, not all files listed in /sys/kernel/cgroup/delegate must exist in every cgroup, so we should ignore ENOENT. Dot not ignore ENOENT on the directory itself though. Change cgroupFilesToChown to not return ".", and refactor it to not do any dynamic slice appending in case we're using the default built-in list of files.

Hmm, apparently the "update with rebase" is working, with all LGTMs left intact, so I have enabled this option for all PRs. See #3407 |
