FWIW, I notice irratic reports about starting avahi-daemon in
shepherd.log ...

g1@g1 ~/bug/30613-avahi-resolve.works.ssh.doesnt/log$ grep avahi shepherd.log 
2018-02-25 22:08:26 Service avahi-daemon has been started.
2018-02-25 22:09:42 Service avahi-daemon has been started.
2018-02-27 08:27:15 Service avahi-daemon has been stopped.
2018-02-27 08:30:53 Service avahi-daemon has been started.
2018-02-27 08:55:23 Service avahi-daemon could not be started.
2018-02-27 11:26:12 Service avahi-daemon has been started.

... and when it does start, a warning about no NSS support in
/var/log/messages:

g1@g1 ~/bug/30613-avahi-resolve.works.ssh.doesnt/log$ grep avahi debug
