Re: [Libguestfs] febootstrap and zypper

Of course "normal" yum commands and suchlike consider what's installed on the host already and only install or upgrade packages. We don't want that behaviour -- hence the complicated Python script (see link in previous email). If there's a way to do all this from the zypper C API, then we could use that instead. Calling out to C from OCaml is simple -- in fact we already do it in libguestfs. See example resize/progress-c.c, or for the real documentation read: http://caml.inria.fr/pub/docs/manual-ocaml-4.00/manual033.html In short, we need a way to download all RPMs, starting at a set of root packages (or root package names), without considering what is installed already.
