示例1: setupConfig
// setupConfig does the following:
//
// 1) creates a directory in the pod's home directory called "config" which
// contains YAML configuration files (named with pod's ID and the SHA of its
// manifest's content) the path to which will be exported to a pods launchables
// via the CONFIG_PATH environment variable
//
// 2) writes an "env" directory in the pod's home directory called "env" which
// contains environment variables written as files that will be exported to all
// processes started by all launchables (as described in
// http://smarden.org/runit/chpst.8.html, with the -e option), including
// CONFIG_PATH
//
// 3) writes an "env" directory for each launchable. The "env" directory
// contains environment files specific to a launchable (such as
// LAUNCHABLE_ROOT)
//
// We may wish to provide a "config" directory per launchable at some point as
// well, so that launchables can have different config namespaces
