Hans (just off-topic, are you by any means from Norway/Denmark?)
If you are thinking about when the kernel-server was hacked, don't worry, md5-checksum is the most secure way to check wether two files are identical to eachother or not, and it was the same when they check it
And for you that are looking for a Linux distro to use, check out distrowatch:
http://distrowatch.com/
They have the most up-to-date database of all of the distro's out there.
However, I'd like to advice the Ubuntu project for you whom are looking for an easy-to-use Linux Distro, and for the ones whom hate Ubuntu, bear in mind that they made "Linux for everyone" a reality with its ease of use.
