Re,
I was able to reproduce the problem. needrestart uses the service name
of $PID retrieved from /proc/$PID/cgroup when the host runs under systemd:
thomas@deje:~$ cat /proc/16880/cgroup
8:perf_event:/lxc/cont1
7:blkio:/
6:net_cls,net_prio:/lxc/cont1
5:freezer:/lxc/cont1
4:devices:/
3:cpu,cpuacct:/
2:cpuset:/lxc/cont1
1:name=systemd:/system.slice/ssh.service/system.slice/nginx.service
^^^^^^^^^^^^^
This happens on systemd but Sys-V init is not affected (since
needrestart won't use the cgroup stuff). Under Sys-V needrestart would
suggest to restart lxc (which might not be reasonable, too).
IMHO needrestart requires (LXC) container awareness and allow to restart
the entire containers or ignore (some of) them by a configuration option.
HTH,
Thomas
