Fool-proof multi-boot PC with Knoppix 6.2.1 run from HD as deault boot option.

[Capricorny]

The reason for this is due to the different versions of mount.
Knoppix 6.2 uses util-linux-ng 2.13.1.1, it is using /dev/loopX, ignoring /dev/loop/X.
New versions of mount found in newer version of knoppix try to use /dev/loop/X, if it is present.

To fix the problem, alternatively :-

   rm -rf /dev/loop

This can be done in either rc.local and any other places suitable.

Maybe. But this is 6.2.1, and /dev/loop/0 is created. And used. But that's the only one, and we need more. So I'm not sure the problem is as you describe.

Try it.

Yes, it works. What I still am not sure about, is the problem description
