I have done my remastering with menu based scripts and are going to use them also in the future! But now I have a problem I can't solve myself.

I would like to use gfxboot as shown in http://www.knoppix.net/wiki/User:Ml#grub_gfx_boot but don't know how to modify these menu based scripts. The problem is action 3. Create isofs. I have tried to modify Knoppix-3.4.mkcompressed but get an error message:
Code:
/KNOPPIX.build/mkisofs: Uh oh, I cant find the boot catalog directory 'boot/isolinux'!
I have changed links from /boot/isolinux to /boot/grub, and boot.cat is where it should be under /boot/grub, but I have not succeeded yet.

Or could someone show me how to create isofs in command line if directory sturcture is as is used in menu based scripts? How to change following lines?
Code:
mkisofs -pad -l -f -r -J -V "MYKNOPPIX" \
-b boot/grub/iso9660_stage1_5 \
-c boot/grub/boot.cat -o ../myknoppix.iso \
-no-emul-boot -boot-load-size 4 -boot-info-table  knoppix_iso_directory
Which directory level should this be run?

EDITED 12.8.2006:
I got it! I run this from /media/hda12/remaster_knoppix5.0.1/KNOPPIX.build/Knoppix.Master/KNOPPIX-CUSTOM/ directory in my system:
Code:
mkisofs -pad -l -f -r -J -V "SuomiKnoppix" \
-b boot/grub/iso9660_stage1_5 \
-c boot/grub/boot.cat \
-o ../SuomiKnoppix.iso \
-no-emul-boot -boot-load-size 1 -boot-info-tab \
/media/hda12/remaster_knoppix5.0.1/KNOPPIX.build/Knoppix.Master/KNOPPIX-CUSTOM/
