Description of problem:

rwhod won't stay up for more than about 2 minutes, then systemd kills it

Version-Release number of selected component (if applicable):

rwho-0.17-36.fc16.i686


How reproducible:

100%

Steps to Reproduce:
1. systemctl start rwhod.service
2. note this doesn't return for 2 minutes; note rwhod runs for 2 minutes
3. note rwhod is no longer running after 2 minutes
  
Actual results:

rwhod not running


Expected results:

rwhod running

Additional info:

 /lib/systemd/system/rwhod.service has been configured with the
PIDFile=/var/run/rwhod.pid  parameter, telling systemd to expect a pid
file when rwhod is happy.

However rwhod never writes a pid file, so systemd kills it after 2 minutes.

In prior Fedora releases, the /etc/init.d/rwhod script did a 'touch /var/run/rwhod.pid' for completeness.

The fix is to remove the PIDFile arg from /lib/systemd/system/rwhod.service,
or to modify rwhod source to get it to write a pid file.
