[Bug 1004320] [NEW] "inet6 static" does not get brought up on boot

[Philipp Wollermann]

Public bug reported:

Ubuntu 12.04 LTS amd64
ifupdown 0.7~beta2ubuntu8

I want to configure eth1 with a static IPv6 address using
/etc/network/interfaces. My config looks like this:

auto eth1
iface eth1 inet6 static
	address fd00:c:a::1
	netmask 64
	privext 0
	accept_ra 0

(I know that fd00:c:a:: is not pseudo-random according to the RFC, but
this network is strictly used for temporary internal testing. :))

After booting, eth1 is "UP", but the static address didn't get assigned,
just a link-local one:

root at phil1:~# ip addr show
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
    link/ether d4:ae:52:89:95:2b brd ff:ff:ff:ff:ff:ff
    inet6 fe80::d6ae:52ff:fe89:952b/64 scope link 
       valid_lft forever preferred_lft forever

When I do "ifup -a", nothing happens, when I run "ifup eth1", it says
"interface eth1 already configured". When I do "ifdown eth1; ifup -a",
the interface gets configured correctly!

Specifying an IPv4 address in addition using a standard "iface eth1 inet
static" block doesn't help. In that case, the static IPv4 address gets
configured correctly on boot, but the IPv6 address still isn't applied.
