Yes.

=================================

However the problem only occurs when I use the following (valid syntax
and configuration) in smb.conf:
=================================
interfaces = 127.0.0.1 172.26.62.112
bind interfaces only = Yes
=================================
If I comment the above out and reboot Samba is live but it's not the
desired configuration.

Also even the more general syntax (again not the desired configuration) fails:
=================================
interfaces = lo eth0
bind interfaces only = Yes
=================================

Seems like a timing issue with Samba being brought up to early. Had a
similar issue with an earlier Ubuntu release that was never resolved.

Title:
  Samba non-functional on boot.

Status in “samba” package in Ubuntu:
  New

Bug description:
  Even though nmbd and smbd are running after boot, Samba service is unavailable.
  ===========================
  ps axf |grep mbd
  2467 ?        Ss     0:00 smbd -F
  2469 ?        S      0:00  \_ smbd -F
  2478 ?        Ss     0:00 nmbd -D
  ===========================

  Samba does not allow connections from other systems and nmap from
  another system does not list ports 139 and 445 as open.

  Restarting both nmbd and smbd after boot makes Samba service available and nmap now shows ports open:
  ===========================
  PORT     STATE SERVICE
  139/tcp  open  netbios-ssn
  445/tcp  open  microsoft-ds
  ===========================
