[Bug 902190] Re: udev fails to update (oneric host, lucid container)

[Serge Hallyn]

** Description changed:

- You will find when running “apt-get upgrade” (if you have Lucid updates
- enabled in /etc/apt/sources.list) that you get this error on upgrading
- udev:
+ ==================================================
+ SRU Justification:
+ 1. Impact: container updates can fail as a result of failed mknods
+ 2. Development fix: allow mknod in containers for all devices (but continue restricting use)
+ 3. Stable fix: same as development fix
+ 4. Test case:  In a container, do 'mknod /tmp/ppp c 108 0'
+ 5. Regression potential: a typo in the template update could break container creations.  However the fix itself will not break containers.  Security should not be impacted as the container will not be able to use the devices it creates.
+ ==================================================
+ You will find when running “apt-get upgrade” (if you have Lucid updates enabled in /etc/apt/sources.list) that you get this error on upgrading udev:
  
  mknod: `/lib/udev/devices/ppp': Operation not permitted
  
  This problem is mentioned on
  https://help.ubuntu.com/community/LXC#Issues and described many places.
  Here are two.

  This seems like an old, known problem, but I did not find a Launchpad
  bug, so I'm filing it.  The change to /var/lib/lxc/server/config seemed
  to fix it for me (though then revealing bug 892892 next).
