Not reinstal, but repair. I'm betting the linux one could be easily repaired via a live-cd. what i want to know is which system was easier to restore back to normal. Not reinstal, but repair.

Boy the computer did not like that. It was funny seeing the computer person trying to fix it. All that would show up was the infamous bomb logo in the white box.

Who the hell approves this shit? if anything.. it's proof you're all either Windows users or Ubuntu zealots. "Linux would not continue with the command until the root password was entered." Wrong. You don't enter your root password, you enter your users password. Deleting all the files in ones C:\ drive is not the equivalent of rm -rf / under Unix, for one, multiple drives are mounted under / on Unix. Anyway, notta-hack god dammit! ban these idiots from posting stupid stories already! This article is full of fail.

Also, files aren't actually unlinked until all handles to them are closed. @Mattos:

When you delete important shit, other important shit dies.... Sure, OS's such as Windows have protections against it, but for Linux/Unix/BSD its just a way to cull the idiots... Hardly hackaday.com quality... Hell, hardly digg.com quality. Is this such a big surprise? When you delete important shit, other important shit dies….

I wonder how many decades it will take before people will get familiar with rmdir, and other 'new' commands introduced after win98..

What struck me as odd was, though, that dpkg/apt-get does not seem to have any kind of "repair"-functionality, that looks through the installed packages file lists, and in case of missing files/wrong checksums for binaries etc, does a reinstall. I had to figure out the broken packages manually, and dpkg -r --force them away, only to reinstall them again.
