Sunburnt;

The compression applied to the elements of the CD are all separate compression methods and independent of each other.

By that, the whole CD is not recompressed several times. The three methods allow what might be termed sub-compressed files in addition to the files generated by the Knoppix Live CD.

It isn't re-compression but multi-compression applied to a cloop-compressed Live CD...appended so to speak with alternate-method compressed files.

I hope this clears up any mis-communication on the issue.
