Yes, but for now, having this work only on Linux would be fine by me;
wecan sort out what needs to happen in Windows later. The important
thing is that we want to offer the same user_data interface across as
many clouds as possible.

I've spent quite a bit of time trying to get that to work, but haven't
been able to. The only extraConfig that you can access within the guest
are properties called 'guestinfo.*', but it seems they can only be set
on running instances. A beer to anybody who proves me wrong on this.
