OK, I'm on jessie which is still on 208. Thanks for your suggestions
howto fix the regex magic... but I consider to drop the call of
systemctl to retrieve the service name. Using screen scraping (on
systemctl status) might be fragile due to:

(from systemctl(1) about the 'status' unit command)
The 'show' unit command does not allow to specify a PID, only names/jobs
are allowed. Maybe needrestart should just read the process's cgroup
file from procfs to find the service name:
clempner:~# cat /proc/`pidof -s apache2`/cgroup
9:hugetlb:/
8:blkio:/
7:net_cls,net_prio:/
6:freezer:/
5:devices:/
4:memory:/
3:cpu,cpuacct:/
2:cpuset:/
1:name=systemd:/system.slice/apache2.service
Viele Grüße,
Thomas
