After zypper dup and restarting all services reported by zypper ps -s on
openSUSE Tumbleweed, USB-hotplug did not work anymore.
Reason is that zypper shows wrong commands and thus not the service, which
needs a restart:


# zypper ps -s
The following running processes use deleted files:

PID   | PPID | UID        | User       | Command     | Service
------+------+------------+------------+-------------+--------
1     | 0    | 0          | root       | systemd     | 
2682  | 2680 | 1366800143 | kukuk      | systemd     | 
24860 | 1    | 0          | root       | udevadm     | 


But PID 24860 is:
root     24860  0.0  0.1  29840  1436 ?        Ss   Nov21   0:00
/usr/lib/systemd/systemd-udevd


Since zypper detects the wrong command and thus does not show, that
systemd-udevd.service needs to be restarted, running udevd and installed udev
rules don't match and in this case e.g. USB-hotplug does not work anymore,
since no more kernel modules get loaded.
