Perhaps I can interest you in a system where the settings, the daemon 
start/run/restart/stop programs, and whatever ancillaries the daemon may 
care to have in its working directory, are all contained in a single 
directory hierarchy, such as /var/sv/syslogd for a 
(non-socket-inheriting) syslogd service.

JdeBP /var/sv/syslogd $ ls
after   conflicts   required-by stopped-by
wants   before  log     service  wanted-by
JdeBP /var/sv/syslogd $ ls service
down    env    restart  run    start  stop
JdeBP /var/sv/syslogd $ ls service/env
flags     oomprotect
JdeBP /var/sv/syslogd $

It is a service bundle, and part of the idea is that it is just a 
directory tree that can be archived up and copied around.  The 
nosh-bundles package contains 739 such service bundles.
