I've thought about that. This is a basically a service, but I can have
multiple instances of the process running with different

We manage many instances of Redis which is somewhat the same problem. I
found it simpler to template init scripts and config files in order to
use the native types within Puppet. The allows sudo service
redis-server-stage restart work without having to refer to documentation
or read what inputs the script needs. Also services start normally when
the box comes up without having to wait for a Puppet run and makes it
simpler to see what should be running on a box or is running.
