Alrighty then. Turns out to be a PEBKAC issue. I was using a ssh2 module for
Node.js that was encoding the result in a Buffer object. This must have been a
recent change & it caught me out. Dumping deviceUpdates ;
{ customCommands: [ [ 'openvpn', <Buffer 4d 57 30 30 30 36> ] ] }
The simple fix was to add a toString() to the result of my custom command ;
return callback(err, result.toString());
