This is a drive-by change after spending some quality time with the mount code. The `id` field of `Mount` is calculated only once and only when creating a `Mount`. This seems slightly dangerous as any change to an attribute after creation will not update the id. This means two options: 1. dynamically update the `id` on changes 2. forbid changes after the `id` is calculcated I went with (2) but happy to discuss of course but it seems more the spirit of the class. It also does the same change for "devices.Device"
