Subject: [PATCH] service: don't create extra cgroup for control process when
9fc0f6
 reloading SysV service
9fc0f6
9fc0f6
Unfortunately common practice in initscripts is to have reload as an
9fc0f6
alias for restart (https://fedoraproject.org/wiki/Packaging:SysVInitScript).
9fc0f6
In that case the newly started process will be killed immediately after
9fc0f6
the reload process ends and its cgroup is destroyed.
