Improve processing of service directories and conf.d files

symbolic links should not be followed in an attempt to work out the name
of the service we are running. Also, @sysconfdir@/conf.d should be tried
as a backup directory for configuration files.

I would like to thank Robin Johnson for his input on this change.
