    on newly created container.

This bug was fixed in the package lxc - 0.7.5-3ubuntu67

---------------
lxc (0.7.5-3ubuntu67) precise-proposed; urgency=low

  * Don't directly write/remove /etc/dnsmasq.d/lxc as that's causing problems
    when removing and reinstalling lxc.
    Instead have dnsmasq ship /etc/dnsmasq.d-available/lxc and create/remove
    a symlink in /etc/dnsmasq.d/. (LP: #1113821)
  * Bump debhelper dependency and add Pre-Depends on newer dpkg for above fix.
  * Allow the container to mount efivars on /sys/firmware/efi/efivars.
    efivars is automatically mounted by mountall on UEFI systems, failure to
    do so leads to a complete boot failure. (LP: #1117589)
  * 0221-make-nonflush-upgrades-robust: be more robust about out of date
    container caches. (LP: #942862)
  * 0207-ubuntu-cloud-fixes.patch: cleanups to lxc-ubuntu-cloud.in
    fix for quantal images that do not have user 'ubuntu' present
    (LP: #1045955)
  * 0301-debian-copy-config: Pass all the arguments to copy_configuration.
    (LP: #1111613)
