Development of Puppet, a declarative language for expressing system configuration, a client and server for distributing it, and a library for realizing the configuration.

Hmmm, so the spec file generates the init scripts, huh?  I guess I don't
know enough about how RPMs work.

Okay, that will work just dandily.  At some point puppetd will also be a
long-running process (and, frankly, that should happen sooner rather than
later), but this is a great solution until then.

Actually I was just following an example, I'm at all not sure whether
that is the 'standard' way of doing things or, more importantly, if it
is the best way. In fact I think it would probably be better if the init
scripts were in the standard distribution.

OK, fair enough. I've modified it so that it is optional and uses
'puppet' by default. Please find the new files attached, with a few
other bug fixes and cleanups too.

I'm going to be away for a couple of weeks, but if no-one else has made
a start I'll take a look when I get back.

Okay.  I, too, think it would be best of the init scripts were in the
standard distribution, although we'll need separate init scripts for nearly
every platform, which is, um, less than ideal.  I hate service management on
Unix.

Great.

I've looked at it, and I definitely want to get this done, but my first
client is using two OSes that don't do packaging all that well (OpenBSD and
OS X), so it's not a huge priority for me right now.
