Knoppix 7.4 - Virtualbox not working

[Werner P. Schulz]

.. if your definition of masochist is "one who prefers good old tools instead of brand new junk.

No, a masochist is for me a person who tries to compile (configure, make and make install) something using an outdated mishmash of an Live system and not using for example the stable release of Debian.

Knoppix is a Live DVD with a mishmash of stable, testing, unstable, experimental and knoppix-debian. All of the 7.4.2 and especially of 5.3.1 moved in the meantime (in spring 2015) to the next level: stable → oldstable, testing → stable and so on. Also many of knoppix-debian has now newer versions.
