Going down this path, even simpler would be to have `supervisord` starting a `tmux` session which starts the Julia app. Then one can simply attatch to the `tmux` session.

I just tried it and I can start a new `byobu` session to start a Genie app with:  
`byobu new-session -s "session_name" "bin/server"`

This can be passed to `supervisord`

Update 1

Unfortunately, not so easy… By default `supervisord` would supervise `tmux` ☹ I think it can be set up so that the Julia app creates a `pidfile` and `supervisor` watches that. Will investigate, but it takes more digging…

Update 2

After more digging it’s a total no go. Looks like `tmux` can’t be started through `supervisor`.
