Already created USB drive of Knoppix, but ...

Hello people!

I've just followed the advice of Josh Krellan based on his notes in Wiki (and originally posted at http://knoppix.net/forum/viewtopic.php?t=25402). And I must say he gave very good details on how to format a USB flash drive into a bootable Linux drive.

I downloaded the Knoppix v5.1 and, following Josh's advice, put it into an 8GB thumb drive and it works. I'm able to boot from it.

However, there is one problem...when all is done and Knoppix booted from the thumb drive, I am not able to do the next obvious thing -- which is to make the USB drive writeable. I followed his example commands: -

mount -o remount, rw /cdrom
mount --bind /cdrom /media/sda4

After having done this, I then opened the syslinux.cfg file using the command: -

vi /media/sda4/syslinux.cfg

But to my dismay, I discovered the file is still in Readonly mode, and I'm not able to change a few lines (as per Josh's recommendations) to modify the Knoppix boot menu.

So, this means that I'm still not able to make the USB thumb drive writeable using the mount commands. Can anyone tell me what went wrong?

Thank you very much.
