I'd prefer that they be consolidated, as well.  As you said, the ip,
extra, etc. variables assume that the guest is Linux.  That is obviously
not always the case.  Having one generic cmdline variable would be
generic enough and keep all of the relevant information in one location.
 Simplifying the config file parsing would also be nice for future
automated tools.

Only one thing comes to my mind: at least ip (not sure which others)
is used for setting up the routes in a routed networking setup, so it
must be kept. Or parsed from the new single commandline variable -
which gets hard when different OSes use different ways to give an ip
on command line. Or worse, if you don't set it on the commandline,
you'd be forced to still write the command line, because it's parsed
for routing.

But when making "ip" indepenedent from the kernel command line, those
users that use routed networking and a static ip given at the kernel
command line, have to set the same information in two places. But I
think that's acceptable.
