Total non-sequitur, but I just read this coming off a 2 day marathon of archive diving on http://xkcd.com and .. somehow.... man. I need to go outside. Watch the rain fall. Have a beer. I couldn't distinguish between your real request for help and the subtle interplay of geekdom and irony on the aforementioned website. I shit you not, I moused over your text 3 or 4 times waiting for the popup with the final punchline. I think I just gave my brain whip-lash. Okay. Back to your regularly scheduled linux.
