[Gnoppix-user] Recreate/Remastering Gnoppix CD

[Danny]

I try to recreate the gnoppix CD with a software I added, but the iso 
file is too big.
I'm following the knoppix remastering guide.
They pipe mkisofs to create_compressed_fs (I guess this is how to put 
the iso smaller), but I can't find it on the gnoppix CD.
Is there a place where I can get this tool or is there another tool that 
comes with gnoppix?
Maybe there is another document to do this with gnoppix.

Thanks,

Danny
