+Yeah that's expected. Everything is a child of pid 1 really, but what

+there are any other processes in between, but I guess not.
+
+&gt;<i> But on the other hand systemd has PID 1 so it's reasonable to assume

+</I>
+Yup.
+
+&gt;<i> Although when I do lsof |grep rsys |grep syst it returns nothing, so
+</I>&gt;<i> perhaps that means rsyslog was not started by systemd: we'd have to compare
+</I>&gt;<i> with a system where systemctl status rsyslog.service gives a better result.
+</I>
+Nah I wouldn't expect rsyslog to know anything specifically about
+systemd, so this would be the expected output.
+
+&gt;<i> &quot;lsof |grep cgrou&quot; returns only one line:
+</I>&gt;<i>
+</I>&gt;<i> systemd 1 root 6r DIR 0,18
+</I>&gt;<i> 0 193 /sys/fs/cgroup/systemd/system
+</I>&gt;<i>
+</I>&gt;<i> I hope this gives some clues.
+</I>
+Sadly not.
+
+What would be useful is to find the pid of rsyslog (mine is 1505), and
+then do:
+[<A HREF="https://www.mageia.org/mailman/listinfo/mageia-dev">root at jimmy</A> ~]# cat /proc/1505/cgroup
+8:blkio:/
+7:net_cls:/
+6:freezer:/
+5:devices:/
+4:memory:/
+3:cpuacct,cpu:/system/rsyslog.service
+2:cpuset:/
+1:name=systemd:/system/rsyslog.service
+
+
+If it looks similar to mine then it has been started by systemd but it's
+somehow &quot;lost&quot; that info.
+
+
+I wonder, do you do anything special with either /var /var/run or /run
+directories? Are they on separate partitions or anything?
