Bug Description

On precise, after apt-get install lxc:

# ip addr show dev lxcbr0
6: lxcbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN
    link/ether 82:6a:90:8b:57:70 brd ff:ff:ff:ff:ff:ff
    inet 10.0.3.1/8 brd 10.255.255.255 scope global lxcbr0
    inet6 fe80::806a:90ff:fe8b:5770/64 scope link
       valid_lft forever preferred_lft forever

From /etc/lxc/default (unchanged):

LXC_BRIDGE="lxcbr0"
LXC_ADDR="10.0.3.1"
LXC_NETWORK="10.0.3.0/24"
LXC_DHCP_RANGE="10.0.3.2,10.0.3.254"
LXC_DHCP_MAX="253"

Expected behaviour: lxcbr0 should be configured to 10.0.3.1/24
Actual behaviour: lxcbr0 is configured to 10.0.3.1/8

This is a problem for me because my setup also uses the 10.x range. 10/8 is too big a range to grab by default.

This bug was fixed in the package lxc - 0.7.5-3ubuntu5

---------------
lxc (0.7.5-3ubuntu5) precise; urgency=low

  [ Robie Basak ]
  * debian/patches/0015-ubuntu-templ-use-updates.patch: use ports.ubuntu.com
    in sources.list for alternative architectures (LP: #820715).
  * debian/patches/0015-ubuntu-templ-use-updates.patch: dist-upgrade in an
    isolated environment to avoid leaving a bind mount behind (LP: #913877).
  * debian/lxc.{default,init}: call ifconfig with explicit netmask
    (LP: #913727).

  [ Serge Hallyn ]
  * debian/lxc.default: update the MIRROR example - using 'localhost'
    fails for updates after the container has been started.
  * debian/lxcguest.console.upstart: pass 'console' not '/dev/console' to
    getty. (LP: #913952)
  * debian/patches/0015-ubuntu-templ-use-updates.patch: at post_process(),
    copy host's /etc/resolv.conf (which may have changed) into chroot before
    apt-get actions, and always do a apt-get update before installing lxcguest,
    as the package version may have changed in the archive. (LP: #914155)
  * 0016-nested-cgroups.patch: nest container cgroups under the host's
    init cgroup. (LP: #901482)
  * 0017-pull-upstream-fedora-template.patch: move to the upstream
    lxc-fedora template (LP: #881903)
  * 0018-make-lxc-ps-search-proc.patch: work when cgroups are mounted with
    '-n'.
  * debian/patches/0019-fix-lxc-ls-nested-cgroups.patch: fix lxc-ls to
    handle the support for nested cgroups. (pull this into previous
    commit msg before pushing)
