[Pkg-samba-maint] Bug#873073: samba: smbd starts before interface is ready, listening only on localhost when "bind to interfaces only = yes"

[Niccolo Rigacci]

Package: samba
Version: 2:4.5.12+dfsg-2+deb9u1
Followup-For: Bug #873073

Dear Maintainer,

I confirm the problem on a host upgraded from Jessie to Stretch.
As a workaround, I added an "up" option to the /etc/network/interfaces:

allow-hotplug eth0
iface eth0 inet dhcp
    ethernet-wol g
    up /bin/systemctl restart smbd.service || true
