I looking to make a mini (185mb or 210mb) knoppix cd. I read in the OSNEWS article that knoppix uses gzip compression. I was wondering if anyone had tried a different compression algorithm or if anyone knows how to make the change. I did a little digging and found UCL:

I have never heard of this before and I really don't know how it compares to gzip. I'd like to hear from anyone who has used it. The other possibility would seem to be bzip2. In his interview, Klaus said it was slower, but he really didn't explain how slow. Has anybody tried bzip2? Is it usable on a modern system?

With such a small space a slight performance hit may be acceptable if it allows increased data storage.
