I would want this for Fedora/RHEL, even if only available via setting some new 
parameter to the service type.  Right now that would mean good old SysV init 
services.  Fedora is going more and more to all native systemd init services, 
but so long as systemd keeps providing backwards compatibility through the 
'service' and 'chkconfig' commands, I don't think puppet has to make any 
special exceptions for that change.

Bug #7165: If services hasn’t started yet, where possible update the file first 
and then start the service.

Category: service
Target version: 
Affected Puppet version: 0.25.5
Keywords: 
Branch: 


Given the following conditions:

1. service 'S' is currently disabled/stopped
1. config file 'F' for service 'S' is currently in state 'A'
1. puppet class 'C' calls for 'S' to be enabled/running and 'F' to be in state 
'B'

When puppet runs, the following currently occurs:
<pre>
notice: //C/File[F]/content: content changed '{md5}-A' to '{md5}-B'
info: //C/File[F]: Scheduling refresh of Service[S]
notice: //C/Service[S]/ensure: ensure changed 'stopped' to 'running'
notice: //C/Service[S]: Triggering 'refresh' from 1 dependencies
</pre>

Thus, puppet sees the service is to be running and makes it so.  Then it 
realizes that a refresh is needed and so restarts the service.  The restart is 
unnecessary in this case.  Depending on the particular service, this could be 
quite undesirable.  Puppet should be able to recognize this case and simply 
start the service just once.
