what is mkdir $ROOTFS/isolinux doing? 1

[dans45]

Hello, I'm trying to remaster the KNOPPIX CD and am having some newbie problems, even following the posted instructions. The last statement in the instructions is :
mkisofs -r -J -b KNOPPIX/boot.img -c KNOPPIX/boot.cd -o myimage.iso NewCD

The problem I have is that there is no boot.img file on the CD. I searched around and found that this could be another file such as isolinux.bin. But when I use this, mkisofs complains that the image is not an allowable size. So I searched for more help. I found another remastering site that says I could use use isolinux as the bootloader.
The first instruction says to make a directory isolinux in the root tree of my rescue system:
mkdir $ROOTFS/isolinux
So I executed this command on my /dev/sda2 drive where I have my new file system but I don't see any output created.
What is mkdir $ROOTFS/isolinux doing?
Thanks, Dan

$ROOTFS is an environment variable that you should set (re-read the page in order no know what value have $ROOTFS). So, if $ROOTFS="/mnt/newCD" then [tt]mkdir $ROOTFS/isolinux[/tt] command will create the directory [tt]isolinux[/tt] in your [tt]/mnt/newCD[/tt] directory.

Cheers.
