But, only Knoppix NOT live cd (with install to HD) source code.

Live CD Knoppix - is a CLOSE source code project!
Boot sector - boot live cd - is a CLOSE code, which NOT include in Knoppix distrib.
Impossible compile from knooppxi distrib to LIVE CD Knoppix.

Such, boot live cd - close code, accroding to GNL, "Live CD Knoppix - is illegal, incorrect.

Such as MS Windows, LIVE CD Knoppix - is a close code project.
