Unicorn migration guide

[Earlopain]

Hey there,

I've been made aware of this project as an alternative to unicorn. It was pretty simple actually given that this started out as a fork but a few things had me thinking about what I need to do. I haven't rolled it out fully yet but cursory results seem pretty good. Would you be open to documentation for people coming from unicorn? I think it would be great to specifically call out actions that need to be taken. Things like:

• working_directory and user (among some others) being removed (favor someting like systemd instead)
• USR2 being repurposed for reforking. I had reload configured in my unit file and my app isn't refork safe
• Linking to https://github.com/Shopify/pitchfork/issues/92 for unicorn-worker-killer
• renaming of after_fork to after_worker_fork

I will open a PR for this if you think it makes sense. There may be other things but this is what I stumbled across.

I also have a question: before_fork was removed early in this repos lifecycle and later added again. Do they behave the same?

Sure.

Mostly yes.
