Comment 2 for bug 1496639

I've just realised there's no bug here. The "default" field indicates if the field is at its default value. It isn't the default value for the field.

For example:

$ juju service get ntp
...
  use_iburst:
    default: true
    description: Use iburst for all servers, not just ntpmaster
    type: boolean
    value: false

$ juju set ntp use_iburst=true

$ juju service get ntp
...
  use_iburst:
    description: Use iburst for all servers, not just ntpmaster
    type: boolean
    value: true
