Ok, this approach does work if rfkill is added to the equation. I
tried it originally
and it didn't seem to. The problem is that my card boots up with
rfkill activated,
and ifup doesn't seem to know about this and reacts strangely.
After boot, it ends up with the interface activated but not working such that a
subsequent ifup fails, then ifdown succeeds, then ifup fails differently (when
rfkill not used). Oddly, when an interactive ifup wlan0 fails, the interface
doesn't end up partly configured: after turning on the radio, a subsequent
ifup wlan0 succeeds. It took a while to sort this out.
It seems to me that either:
ifup should make sure to rfkill unblock wifi or the like, or
ifup should fail and leave the interface fully unconfigured on boot
Here's a log showing the current behavior:
