Public bug reported:

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.
