I guess the = breaks the search; it's discussed in CONNECTION SECTION line 389 connection.mdns If unspecified, the ultimate default values depends on the DNS plugin. With systemd-resolved the default currently is "no" (0) and for all other plugins also "no" (0). There actually is a reference to nm-settings just above. line 369 Not all properties can be overwritten, only the following properties are supported to have their default values configured (see nm-settings(5) for details). A default value is only consulted if the corresponding per-connection value explicitly allows for that.
