Something that would be useful for scripting but looks missing is the ability to exec another process directly. My use case here is we have docker containers that I'd like to run a planck script on startup, and then exec a long-running java server process.

I'll file a ticket if you agree

Yeah, I think that makes sense... the Planck process would effectively disappear, leaving the other one running

Normally a docker container exits when the initial process terminates I've learned, hence the need to exec
