+1 we were running a networkmanager dispatcher[^1] for cases like this :)

I have some hosts which converted to systemd-networkd (which doesn't
support hooks by now), and most of the time, tinc simply won't come up
after bootup (or won't be able to reconnect when the network is
changed), which is really ugly.

Having a local dns in front is somewhat hacky, I'd really love if tinc
would simply reload /etc/resolv.conf each time a new metaconnection is made.

It's fixed in git now; res_init() is explicitly called before every call
to getaddrinfo(). I hope some day the glibc maintainers will see the
light that /etc/resolv.conf is not a static file.
