Booting the machine.

I wrote this that restarting samba with systemctl just didn´t change that 445 
is still listening on localhost (and thus it does not seem to be needed to be 
accessible by client machine).

Then it works.

I don´t really need them, but I think they can be an additional security 
precaution and it may be needed for servers with additional interfaces.

Please, pretty please do not hint at what RHEL 7 is doing there by requiring 
Network Manager on every system.

I have:

allow-hotplug eth0
iface eth0 inet dhcp

No Network Manager.

And I think this should work *out of the box*. It certainly did with Jessie.

Also it doesn´t work when I use:

root at fileserver:/etc/systemd/system# cat smbd.service 
[Unit]
After=network-online.target nmb.service winbind.service

Feel free to reassign this to either systemd or ifupdown.

I bet upon a release of Stretch with this unfixed will break a ton of setups 
out there. So at least this behavior should be mentioned in release notes IMHO 
and/or in an debconf prompt.

Thanks,
