USB booting :: IFCONFIG Help

Damn, so easy?

Ive made a small ext3 partiton (~300MB), copy /KNOPPIX/* to a new directory like /mnt/KNOPPIX, change my configuration and do
mkisofs -R /mnt/KNOPPIX | create_compressed_fs - 65536 > /mnt/newKNOPPIX/KNOPPIX
and change it with the /KNOPPIX/KNOPPIX from the USB-Stick

But it works
