Alright, I’ve started work on an initial patch (to Kevin Anderson’s patch).

There was a bit of discussion on GitHub:
Recently (259e170) a fruit:model option was introduced to configure what Samba sends for the AAPL_MODEL_INFO extension.
Apple also uses the _device-info._tcp advertisement for the same purpose.
The main effect of both is what icon is used in Finder, with _device-info._tcp taking priority.
Should I also configure that advertisement? I don’t know if it matters much either way.
Netatalk uses it, but I don’t think it has anything like the AAPL_MODEL_INFO extension.
