It's still 4.1. You surely aren't planning to take 4.2 for (frozen)
Wheezy?

So? This isn't fixed in -4 either as far as I can tell. Nothing of any
relevance to this bug has happened between -2 (in Wheezy) and -4 (in
Sid).

Yes, I obviously know this. I made all of these changes upstream,
including making the equivalent xend changes for 4.2, so I'm not sure
what you are trying to tell me.

xend in 4.1 needs a fix as it has not been modified to do tap hotplug
via udev.

As I said before I don't think it would be wise to backport the xend fix
from 4.2: it is far too intrusive and too risky (I made the same
determination for the upstream stable backport and I am of the opinion
that it is not good for Wheezy either).

The right fix for xend in 4.1 for Wheezy is to take the one liner patch
to qemu-ifup which I posted earlier in this thread. Do you disagree with
this assessment?

Ian.
