And I found it worked well, assuming I set up the virtual interfaces beforehand, which I did via ifupdown because that's what I had experience with. It's possible I want to just jettison ifupdown entirely and use a custom script to handle it at boot time: I don't love that, but the cross-purposes between all of these packages might make the result too fragile to rely on, especially across upgrades that might make a machine suddenly unreachable on boot.
