Attaching backport of the patch for utopic.

** Description changed:

- When restarting the puppetmaster process (via the service command, or
- calling the initscript directly), the restart can fail if the original
- process does not exit immediately. This is because the initscript is not
- written to wait for the original process to exit.
+ [Impact]
  
- In my testing under Trusty, adding "-R n" to the start-stop-daemon
- command in the initscript fixed the problem. It's difficult to determine
- an appropriate value for n, but it could be tunable via
- /etc/default/puppetmaster. It's definitely a problem not to wait at all
- for the process to exit.
+ Users restarting puppet and puppetmaster may have problems restarting the
+ daemons, in systems under heavy load may be more frequent, because if the stop
+ operation takes more than 1 second the start operation fails due that the
+ daemon is still running.
+ 
+ If the daemon isn't started in a machine managed by puppet (or the
+ puppetmaster) will require manual intervention to bring up the system.
+ 
+ [Test]
+ 
+ - Create a small VM (512MB, 1 vcpu)
+ - Install puppet and puppetmaster packages
+ - Restart each daemon twice with a 10 seconds pause
+   # service puppetmaster restart; sleep 10; service puppetmaster restart
+ 
+ Expected results:
+ 
+ - The service is restarted
+ 
+ Actual results:
+ 
+ - The service is stopped, but it isn't started again the console prints:
+ 
+ root@vivid-puppetmaster:~# service puppetmaster restart ; sleep 10 ; service 
puppetmaster restart
+  * Restarting puppet master
+    ...done.
+  * Restarting puppet master
+    ...fail!
+ 
+ [Regression Potential]
+ 
+ - If after 10 seconds the daemon isn't exited the start-stop-daemon command
+   will send the KILL signal and wait for 5 seconds, this is different from the
+   current behavior that just informs the restart failure to the user and
+   doesn't send the KILL signal.
+ 
+ [Other Info]
+ 
+ When restarting the puppetmaster process (via the service command, or calling
+ the initscript directly), the restart can fail if the original process does
+ not exit immediately. This is because the initscript is not written to wait
+ for the original process to exit.
+ 
+ In my testing under Trusty, adding "-R n" to the start-stop-daemon command in
+ the initscript fixed the problem. It's difficult to determine an appropriate
+ value for n, but it could be tunable via /etc/default/puppetmaster. It's
+ definitely a problem not to wait at all for the process to exit.
