Comment 10 for bug 1506521

@chris -- as the initial bits of this have now gone out (the conversion to python3) if there is a remaining issue with netmask handing that is likely separate issue. Either way could you please create a new bug for me and link it from here (and if you are able let us know the number of #ubuntu-kernel), and include the ifcfg-eth0.

If I am reading that right you have a NETMASK0 in there which sounds like something we would not be expecting. All the parameters are like FOO, FOO1, FOO2, so NETMASK0 I think we are expecting to be NETMASK. Though regardless it would be possible to support both. Do attach the generated ifcfg-eth0 to that new bug for completeness.
