I'm saying most aspects of it can be solved within the program -- anything 
except 'kill -9'. With something like upstart, even that should be solvable. 
On OS X, I think launchd is similar. Basically, you have one (or more) central 
process(es) which manage the launching and killing of daemons.

At this point, you don't even have to use pidfiles, you can just use 
variables. In pseudocode:

class Process
  def start
    unless running?
      if @pid = fork
        waitpid(@pid) do
          @pid = nil
        end
      else
        exec @cmdline
      end
    end
  end
  def stop
    kill @pid
  end
end

The main reason that's pseudocode is that upstart very likely already does 
this for you (so why reinvent the wheel in Ruby?), and because waitpid doesn't 
actually work that way.

But basically, the only problem with this model is that if the process 
responsible for watching your process dies abnormally, either the pidfile 
won't be cleaned up (if there is one), or you'll now have an unmonitored copy 
of your process running (so you'll need something like killall again). If 
you're using something like upstart, that's not really a problem -- remember, 
upstart is init, which means the second it dies, the kernel panics. In other 
words, it doesn't die.

The usual approach I'd suggest here is, store a configfile path, something 
like the PATH variable, in which later configfiles override values set by 
earlier ones. Then, set all the default values in a sample config file inside 
your gem, and let the admin put a conf file in /etc/rb_app (or in ~/.rb_app, 
or in a place specified by the environment variable RB_APP_CONFIG, or in a 
place specified by --config on the commandline) if they want to override 
something.

That just leaves this part:

That much is possibly true -- you'd need a script that installs/updates that 
script.

If you're worried about people going so far as to have separate Ruby 
interpreters, I'd suggest letting them write their own script, and simply 
provide documentation, and maybe a command to install some default samples. 
Those scripts would likely be very simple anyway.

On the other hand, you might consider just building a Debian package, 
depending on the interpreter you want, and hardcoding it into the shebang and 
the upstart scripts. Let people download the source if they want to tweak it 
further. But I'd only go this route if you're content to depend on the Ruby 
libraries that are already packaged in Debian -- unlike some other package 
managers, apt lacks a way to depend directly on truly alien packages. 
(Contrast to Gobo, in which system packages can depend directly on gems, CPAN 
modules, etc -- I know Gentoo could depend on CPAN modules, too.)
