The hostname is updated via /etc/dhcp/dhclient-exit-hooks.d/hostname
(like it is done in wheezy). But for some reason it now takes about 15
minutes to take effect if a new or just renamed system is connected.
Running 'systemctl restart networking.service' updates the hostname
immediately. (As observed since a long time in a d-e virtualbox
environment.)

I just had the chance to test this w/ real hardware, same behaviour.
