[Samba] Right-way to use " bind interfaces only = Yes"?

[Gilles]

Hello,

Is  "bind interfaces only = Yes" a good thing to use, and in that case, 
what's the right way to fix it 
<https://askubuntu.com/questions/108040/samba-needs-additional-restart-on-reboot/349142#349142> 
(on Debian)?

If I use it, Samba only listens to the loopback interface.

Thank you.
