Comment 120 for bug 1754671

The backport is quite complicated due to several changes that made the
DNS code in nm-1-12 diverge from nm-1-10. The th/policy-and-mdns
branch [1] alone changed:

 src/dns/nm-dns-dnsmasq.c | 330 +++++++++++++--------------------
 src/dns/nm-dns-manager.c | 581 +++++++++++++++++++++++++++++++++-------------------------
 src/dns/nm-dns-systemd-resolved.c | 219 ++++++++++++++--------

so, unless we decide to also backport that branch, the backport of the
fix requires reimplementing several non-trivial patches on top of
1.10, with the high risk of breaking things.

If we also backport the th/policy-and-mdns branch, we would need to
backport a total of 30+ commits, including mDNS support and related
libnm API.

Any opinions? This latter approach seems doable, but it is a big
change for a minor release.
