Comment 4 for bug 1869629

This problem is indeed somewhat pervasive, I also filed bug 1869632 on cups-browsed doing the same thing, for the same reason. I suspect more will pop up. I don't think libnss_mdns is too widely used, most people would use libnss_mdns_minimal. I only have to use libnss_mdns because my ISP is insane. If this bug were fixed by adding /etc/mdns.allow to /etc/apparmor.d/abstractions/mdns bug 1869632 would be fixed as well (I've verified this by patching it on my system.)

Not sure why /etc/apparmor.d/abstractions/mdns contains /etc/nss_mdns.conf, though: libnss_mdns.so.2 doesn't refer to that file (it appears to be used in the NetBSD implementation?)
