Oh yes, I should have said this: that is indeed the problem. (Well
deduced!)

Yes, it does, but having a look at /usr/bin/lxc-update-config, I see
that the "0" in this is not necessarily always correct; it could be
any number. So perhaps something more like:
local bridge_interface=$(awk '/lxc\.net(work|\.[0-9]+)\.link/ {print($3)}'
/etc/lxc/default.conf)
would be better?
Best wishes,
