Description of problem:
I have 2 service files: ups-driver.service and ups-daemon.service Driver should start when starting daemon and should stop when stopping daemon. Right now, it is started automatically when starting daemon, but it does not stop after daemon is stopped. There is also unexpected systemd message about stopping driver when daemon is started.

Version-Release number of selected component (if applicable):
systemd-26-1.fc15.x86_64

How reproducible:
always

Steps to Reproduce:
1.you need configured nut and nut-client
2. cat /lib/systemd/system/ups-driver.service 
[Unit]
Description=Network UPS Tools - driver
After=local-fs.target network.target
StopWhenUnneeded=yes

[Service]
ExecStart=/sbin/upsdrvctl start
ExecStop=/sbin/upsdrvctl stop
Type=forking

3.cat /lib/systemd/system/ups-daemon.service 
[Unit]
Description=Network UPS Tools - daemon
After=local-fs.target network.target ups-driver.service
Requires=ups-driver.service

[Service]
EnvironmentFile=/etc/sysconfig/ups
ExecStart=/usr/sbin/upsd $UPSD_OPTIONS
Type=forking

[Install]
WantedBy=multi-user.target

4.systemctl --system daemon-reload
5.systemctl start ups-daemon.service
  
-> both ups-driver and ups-daemon are running, but /var/log/messages contains odd messages from systemd:
14:08:42 systemd[1]: Service ups-driver.service is not needed anymore. Stopping.
14:08:42 krles systemd[1]: Requested transaction contradicts existing jobs: File exists
14:08:42 usbhid-ups[3903]: Startup successful
14:08:42 systemd[1]: Service ups-driver.service is not needed anymore. Stopping.
14:08:42 systemd[1]: Requested transaction contradicts existing jobs: File exists
14:08:42 upsd[3904]: listening on 127.0.0.1 port 3493
14:08:42 upsd[3904]: listening on ::1 port 3493
14:08:42 upsd[3904]: Connected to UPS [myups]: usbhid-ups-myups
14:08:42 upsd[3905]: Startup successful

(usbhid-ups is started by upsdrvctl from usp-driver.service)

6.systemctl stop ups-daemon.service
7.systemctl status ups-driver.service

Actual results:
ups-driver running:
ups-driver.service - Network UPS Tools - UPS information server
          Loaded: loaded (/lib/systemd/system/ups-driver.service)
          Active: active (running) since Thu, 12 May 2011 14:08:42 +0200; 2min 32s ago
         Process: 3901 ExecStart=/sbin/upsdrvctl start (code=exited, status=0/SUCCESS)
        Main PID: 3903 (usbhid-ups)
          CGroup: name=systemd:/system/ups-driver.service
                  └ 3903 /sbin/usbhid-ups -a myup

there are no extra messages in /var/log/messages, just ups-daemon messages about termination

Expected results:
ups-driver stopped
