  Everyone makes mistakes  I've pushed a patch so it now gives an *error* message \
saying "no such file".  That's a lot more useful than "failed".

  The fields are attribute names.  You *cannot* use %{...} expansions.  You *must* \
place the expansion into a temporary attribute, and then use that.

  That one should work.

  Neither of those will work.  e.g. there is no attribute named "%{DHCP-....}"
