ok. It should be understood that the 'Remastering HowTo' that I refer to is NOT the 'HDD HowTo' but the standard chroot method.
See this Link:

Sorry if that has confused anyone!
So all I am saying is that your standard chroot remastering enviroment is normally '/mnt/hda1/knx/...blah blah'
However, your Knoppix type hdd install will be '/mnt/hda1/ ..blah blah!' so you have to take this into account.
Your boot image/syslinux/isolinux/miniroot.gz (depends which Knoppix you are using i.e <=3.3 or =>3.4) must be on a seperate partition. Hence I use '/mnt/hda3/knx/master/KNOPPIX' for simplicity. Hda2 of course, is swap partition.
I'm no expert but to simplify the layout, hda1 is your main customisable part of your OS (apt-getting and all that) and hda3 contains your 'booting up' part of the CD (cheatcodes/hw params etc).
Hope that helps (a little..)
