DHCP issues 1

[Leslie Rhorer]

	I posted previously about the issues I am having.  Nothing I tried, 
including completely purging and reinstalling isc-dhcp-server, would get 
DHCP to work on my secondary server, so I completely wiped the server 
and reloaded the OS.  The server is mostly working now, but there are 
still some annoying issues. Stopping, starting, and restarting the 
server don't quite work properly.

	1.  Systemd reports a spurious error when starting the server from a 
clean slate.

	It doesn't say what the error is, but the exit code is 1. This causes 
the system to think the server has failed to start, but it does load and 
remains in memory.  It seem to be working pretty well.  Is there some 
way to get the server to report a bit more in the way of diagnostics, 
perhaps in the log, or even just stderr?  Obviously, this isn't a show 
stopper, but it is a bit annoying, and it is possible there is something 
a bit more insidious going on.

	I tried running the server from the CL with the -d option, but it 
doesn't produce any output.
