// TODO(wad) This is a placeholder DBus service which allows
//           chrome-login (and anything else running as chronos)
//           to request to mount, unmount, or check if a mapper

//           into C++.
//           We will need a "CheckKey" interface as well to simplify
//           offline authentication checks.
