Conditionally adding A records in conf.c is a rather fragile approach

[fzs]

Right now A records are only added when the interface already has an IP address. This works, because the whole configuration is reloaded when something changes, but it is rather fragile. It would be preferable if A/AAAA records were added dynamically when the interface IP changes. This is currently not implemented in the library because it needs external information like the conflict callback and hostname. Maybe a better solution can be found.

	/* If an IPv4 address is already set, add an A record for it. */
	struct in_addr ipv4addr = mdnsd_get_address(d);
	if (ipv4addr.s_addr != 0) {
	r = record(iface, 0, NULL, nlocal, QTYPE_A, 120);
	mdnsd_set_ip(d, r, ipv4addr);
	}
