[Bug 1182655] Re: Samba printers are missing after reboot until smbd is restarted

[floid]

Noticed today as well on 13.04 (64-bit).

The "reload-smbd" upstart script already exists to handle this per the
prior bugs, but apparently something's still racing.

-rw-r--r-- 1 root root 213 Nov 23 08:55 /etc/init/reload-smbd.conf

smbd.log appears to suggest that the reload isn't happening (boot at
13:00; manual restart of smbd when printing issue noticed at 14:23):

Title:
  Samba printers are missing after reboot until smbd is restarted

Status in “samba” package in Ubuntu:
  Confirmed

Bug description:
  This may be related to
  https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1010501
  and
  https://bugs.launchpad.net/ubuntu/lucid/+source/upstart/+bug/494141

  After a reboot Samba printers are not visible until smbd is restarted. 
  I've tried adding "and started cups" to /etc/init/smbd.conf but that only seemed to work very intermittently (I'm guessing this caused a race condition). I've also tried adding "and started smbd" to /etc/init/cups.conf but that didn't work at all. The only thing that seems to have worked is the patch in this comment https://bugs.launchpad.net/ubuntu/lucid/+source/upstart/+bug/494141/comments/18

  Steps to reproduce
  1. Reboot a samba server with printers shared through samba
  2. Run "smbclient -L COMPUTER -N" after it comes back up

  What is expected:
  Samba printers should be listed under Sharename in the output from the smbclient command above or to Windows clients

  What happens instead:
  Printers are not available through samba until smbd is restarted
