Newbie: using kpackage (?)

[under]

I've just chroot using:

chroot /mnt/hda1/knx/source/KNOPPIX
Now my question is can I use kpackage to add rem packages from my custom knoppix ?
i think the right command is:

export DISPLAY=localhost:0.0
kpackage
Am I wrong ? Is this possible without crash my custom version ? :D

According to http://www.knoppix.net/wiki/Knoppix_Remastering_Howto, you'll need to outside of the chroot run

Xnest -ac :1

Back in the chroot, you need to

export DISPLAY=localhost:1

This part of the How-To worked fine for me. Hopefully it will work fine for you.
