Like I mentioned, this is further down in my list of priorities at the moment (e.g. not-started external vkernel shutdown & other ideas, etc much more fun) .. Let me know if I should file a bug or similar to track things, otherwise I'll probably leave in the back of my mind to gather dust. Thanks, - Chris

Yes. By the way it does not really matter where the sources are located as long as you have enough disk space. ;-) -- Gergo Szakal <[EMAIL PROTECTED]> University Of Szeged, HU Faculty Of General Medicine /* Please do not CC me with replies, thank you. */
