    Excerpt

    can just, for the life of me not get this to work. I don't have a system json entry in my config.gateway.json... and when i try to add the section [and I add it correctly as JSON object] it just gets the USG stuck in provisioning mode when it tries to pull down...I have tried inserting the code with necessary trailing comma - at the start of the file [after opening bracket... but fails.
