An error indeed. The problem was that bootfrom does not appear to work, even though it is listed. Someone suggested fromhd as an alternative. The response from Klaus here confirms my response to that suggestion by agreeing what fromhd does.

However we still have no confirmation on the possibly defunct status of bootfrom.

That was me and I was mistaken.

I use fromhd=. I've a set up that boots a hard drive with a syslinux.cfg that uses fromhd= to boot a USB stick. Sounds stupid but I want my persistent image to be portable and home=is not implemented for Knoppix 6.

I also booted the USB stick and used fromhd=/dev/sr0 to boot Knoppix on DVD. Hence my confusion. I think of a CD/DVD as an iso file, which of course, it isn't: it's a burnt iso file.

I suspect that once upon a time someone found they were burning an excessive number of CDs while testing an upcoming Knoppix release so they added the bootfrom= cheatcode to save time and money. These days, I suspect, most of the testing is done using fromhd= to boot the KNOPPIX/KNOPPIX file. Since bootfrom= was a cheat code for developers they saw no reason to support any more.

The file knoppix-cheatcodes.txt still talks about "knoppix.sh", which I know does exist in Knoppix 6. The problem here is not that a single cheat-code is obsolete. The whole text has to be read with extreme caution. The same goes for the (English) wiki. Who updates that ? Is it up folks like us ? (The blind leading the blind comes to mind).

I'm thinking I might be better off joining the German language forum. Ich kan Deutsch nur ein bisschen. So I wouldn't be posting but what I read might be most helpful.

No, wrong again.

I read

Knoppix 6.1 ignores the knoppix.sh file. use the overlay-(ext2)filesystem /mnt/system/KNOPPIX/knoppix-data.img instead.

on the Wiki page http://www.knoppix.net/wiki/Knoppix_Remastering_Howto.

I don't know what that sentence is trying to say but for Knoppix 6.4.3 at least, a file at

/mnt-system/KNOPPIX/knoppix.sh

works.

Great if you have a USB install as no remaster is needed. Bad if you've a CD/DVD (comes back to the lack of home= again) as you'd need to remaster after every change.
