[Bug 602744] Re: LTSP client can not run local apps after server is shutdown before client logs out when /tmp is not cleared on next boot.

[Frederick J. Henderson]

Just wondering if this has been fixed or if no one else has experienced
it that it has not been changed in priority. Would be nice to at least
see its status changed to confirmed even if it does no get assigned to
someone to fix right away. Admittedly this would be low priority as it
should rarely occur, but it could be a frustrating experience for a LTSP
administrator that does not know about it.

Title:
  LTSP client can not run local apps after server is shutdown before
  client logs out when /tmp is not cleared on next boot.

  Expired

Bug description:
  Hi!

  I discovered this bug because of another bug that did not clean /tmp
  out on each boot.

  https://bugs.launchpad.net/ubuntu/+source/mountall/+bug/602723

  I accidentally shut the server down while on client was still logged
  in and working. This is possible from the Gnome server login by
  selecting shutdown. It is not possible if I am logged in and try to
  shutdown there in tells me I need to give a root password as the
  system policy prevents shutdown while other users are logged in. That
  however is another bug report for me to file.

  Upon the next boot the only the client that was logged in was no
  longer able to run some local applications. Other terminal were
  functioning normally. Other users logging on the client that was not
  shut down properly had the same problem. For example opera would start
  but the gui interface would never show. If you try to start Opera
  twice it pops up a window telling you.

  Running ltsp-localapps xterm would start an xterm window, but running
  either of the commands ps or ls would cause the xterm window to
  freeze. I could however run top and pwd.  Using Ctrl-Alt-F1 to go to
  the root terminal and I got the same results.

  I used the fix in the bug report above so that the /tmp folder would
  be cleared. Rebooted and everything works as it should.

  This is a problem that should be fixed as it is possible for a user to
  set their /tmp folder to only clear files older that a certain age.

   LTSP needs a way to cleanup its temp files on reboot if they exist in
  /tmp. I can only image how much grief this would cause a LTSP admin on
  Lucid when someone accidentally shuts the server down with say 25
  client connected and now 25 machine will not run local apps.
