## -----------------------------------------------------
## Maintain a tiny window for rename to avoid contention
##   - Validate download by displaying version
##     - --version not supported by wget binary
##   - Detection and error recovery possible if release
##     binary corrupt or mia but potential for stale
##     command version to silently persist is a larger
##     testing issue so explicitly overwrite.

## -----------------------------------------------------------------------
## Infinite loop -- huh(?!?)
## Interrogate voltctl startup for status to avoid potential for
## container accumulation when downstream container shutdown fails.
## -----------------------------------------------------------------------
## If sleep is intended to keep the container alive for downstream tasks
## use handshakes and/or timeouts to avoid long term, idle, resource retention
