the debian-add_ip.sh script available in vzctl 3.0.23 does not set up
IPv6 default route correctly for a Debian 5.0 (Lenny) container.
The reason seems to be that the default behaviour of the ifconfig
command changed from etch to lenny: when adding IPv6 addresses without
specifying a prefixlen, the prefixlen is assumed to be /128 in Lenny
instead of /0 in etch.
The patch below corrects the problem by explicitely specifying the
prefixlen, and works for both Etch and Lenny containers.
