Subject: [PATCH] service: don't create extra cgroup for control process when
reloading SysV service
Unfortunately common practice in initscripts is to have reload as an
alias for restart (https://fedoraproject.org/wiki/Packaging:SysVInitScript).
In that case the newly started process will be killed immediately after
the reload process ends and its cgroup is destroyed.
