Ideas

- Review of config labels:
  - `*Timeout` has no time units
  - Is seconds the right resolution?
- Need to document update JSON format used for update.exe - top of file?
- Upgrade checksums - remove MD5?  Secure?
- Certificate enforcement in update check - lock to a domain
-  `.reload` vs `.restart` ?
- Review check check "operations".  The name "actions" and "args" seem inconsistent.
