Adding a vlan brings up all interfaces

[Andy Lutomirski]

I have a relatively straightforward /etc/network/interfaces configuration, like this (excerpted):

auto p3p2.1
iface p3p2.1 inet static
    vlan-raw-device p3p2
    ... configuration here...

auto p3p2.2
iface p3p2.2 inet static
    vlan-raw-device p3p2
    ... configuration here...

The problem is that ifup p3p2.1 (or ifup p3p2.2) brings up both p3p2.1 and p3p2.2. In fact, vconfig add p3p2 1 brings up both interfaces.

The problem seems to be that /etc/init/network-interface.conf says "start on net-device-added". The intent is (presumably) to start the interface when p3p2 is added, but not to start p3p2.x when p3p2.y is added.

This is particularly annoying because ifdown p3p2.2 deletes the interface, so I can't reliably bring down two vlans and then bring just one of them back up.
