I just got SuperRescue working on my box. It is much slower compared to Knoppix, how does Klaus boot the thing so quickly? Knoppix boots just as fast as my harddrive install (RedHat 9.0). How different is Debian in the way things are run, I may consider running Debian from now on

Yes, the thing is that having the data compressed on the CD makes it read faster, because it's faster to read say 400kb from the CD and uncompress it to 1Meg, than it is to read 1Meg uncompressed. This is becasue the CD read speed is the bottleneck in the whole process.

Debian is probally slightly faster than RedHat at booting. But you should consider running Debian for many more reasons than that... ( apt-get, way more available packages, easy upgrades .. etc etc )

thanks for your take, for now, I will most likely do a remastering of the Knoppix cd to add custom software that I use. I believe that SuperRescue uses zisofs which compresses the data with a 2:1 ratio or so, I was not impressed at all with the speed that it booted with, but I liked the two things about it (it requires you to login upon startup, and kudzu for hardware detection) (this would be good to restrict access so that someone does not have total control of your computer). How does Klaus optimize the cd for speed when remastering it?

Another question, if I were to use cloop compression on making an iso image of mp3's (which are already compressed), would I get any compression out of them? If I could do that, I can pack nearly 2.0 gb of music on a cd and 12 gb on a dvd or so. CDROMs are in every computer just about so this would help make the distro run on any machine.

Thanks much,
Walter
