I've been playing with shepherd and service configurations and it's
actually easier than I thought it would be, at least for "simple"
services. Thanks for showing me the way! :-)

I love it so much that I started/stopped the emacs service (defined with
the snippet above) a few times. It works as expected, except for
the `defunct` processes that hang around. Each time I run `herd stop emacs`,
I get a new one, as if shepherd could not forget about the dead process.
This doesn't prevent me from re-starting the process and using the service,
but it looks… messy!

Am I doing something wrong?!
