Hi Joe

https://github.com/skunkwerks/hello/ contains about 80% of a blog post in the
README, it's a minimal phoenix project with the build goop to produce a native
FreeBSD package. This, and pkg-repo behind a webserver allows you to
deploy only with pkg.

I stripped out all the (IMO) messy bash scripts, and the rc.d script does the
minimum needed. I assume in most cases you'll want to use distributed
erlang and you either pass that in with erl_flags or in vm.args as appropriate.

It's possible to add extra stuff in the manifest to start or stop your app
directly, but I prefer to do that via ansible.
 
Let me know if anything's not clear. I hope it's useful for you, and PRs are
welcome for any improvements.

A+
Dave
