Hi again all,

I have been playing around with the KNOPPIX file stripping stuff out I dont need, installing programs I do etc, which is all good... But when I go to make the new ISO file its huge!

I had a 58meg KNOPPIX file used:

mkisofs -no-pad -l -r -J -no-emul-boot -boot-load-size 4
-boot-info-table -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat -hide-rr-moved -o newdsl.iso /mnt/hdb1

and I got a 599meg ISO file! When I did the same thing to a 52meg KNOPPIX file I ended up with a 1.2gig ISO file!!, smaller KNOPPIX file bigger ISO file... somethings wrong me thinks!

Can anyone please let me know what gives here and how I can make a much much smaller ISO file.

Thanks in advance

What do you have in /mnt/hdb1? Everything on that partition will be added to the iso with the command you used.

Ah ha!

That would explain it then, I knew I was doing something not quite right. What should I add to the command to only do that 1 file plus the boot files? I have played around with it a bit but if I do try and change the final path (/mnt/hdb1) it always says "oh no can't find the directory /boot/isolinux".

Thanks for all your help

well, what i've done is make a directory and put all the relevent files into that: boot/, KNOPPIX/, and optional/ if desired. Enter that directory and run the same command you have, but using "./" instead of "/mnt/hdb1", and "../newdsl.iso" instead of "newdsl.iso"
