Function script 

pub fn script(c: &Configured<'_>, resources: &[Resource], fresh: bool) -> String

A VM’s set-up step for resources, a run of the recipe between its scripts and reboots: the library, then each step’s call, from the project folder. fresh: no script, playbook or reboot ran before it in this apply, so nothing has changed yet; otherwise one may have, and the services after it restart (the rule errs on restarting).
