David M. Lyle commented on METRON-897:
--------------------------------------
Now that I look closely at it, I'd prefer not to default to eth0, with or
without brackets. That seems brittle. How would people feel about binding to
all interfaces by default. IIRC, that is achieved by setting network.bind_host
to 0.
