In my continuing quest to reduce periodic/daily email to something that
can actually be read and understood at a glance, I've come up with the
following patch, which strips uninteresting interfaces and link-level
data from the output of 420.status-network:

Index: 420.status-network

Instead of this:

Network interface status:

I get this:

Network interface status:
Name    Mtu Network       Address              Ipkts Ierrs    Opkts Oerrs  =

   -

BTW, I think daily_status_network_usedns should be off by default.
