Function configure 

pub fn configure(
    c: &Configured<'_>,
    resources: &[Resource],
    fresh: bool,
    index: usize,
) -> Configure

The index-th configure run of machine c, its resources and fresh flag as the shell renderer takes them (see shell::script): the script compressed into a write_files entry and the runcmd that runs it. A machine’s runs are numbered from 0, in set-up order.
