[Bug 1648068] [NEW] systemd-resolved.service hangs a long time on shutdown

[Martin Pitt]

Public bug reported:

On shutdown or "systemctl stop systemd-resolved" you get a long hang:

● systemd-resolved.service - Network Name Resolution
   CGroup: /system.slice/systemd-resolved.service
           └─control
             ├─15479 /bin/sh -c [ ! -e /run/resolvconf/enable-updates ] || /sbin/resolvconf -d systemd-resolved
             ├─15480 run-parts --arg=-d --arg=systemd-resolved /etc/resolvconf/update.d
             ├─15483 run-parts /etc/resolvconf/update-libc.d
             ├─15497 /bin/sh /usr/lib/avahi/avahi-daemon-check-dns.sh
             └─15509 host -t soa local.

So that resolvconf hook tries to do name resolution which does not work
any more at that time.
