fusecompress on knoppix-data.img?

May I suggest that you seem very optimistic about the situation?

Yes I am. Because I update my kernel very often, each time I have to match it against the correct version of aufs. I have compiled aufs kernel module too many times already.

First, aufs is a general tool, and it is used "everywhere", not only in Knoppix. The message I linked to was in response to a Debian user. A "typical" Debian user may not need it, true. But many essential libraries are never required by "typical" users, still they are essential.

I don't know what "essential" libraries you are talking about. A typical aufs user does not even use the aufs tools. Even knoppix does not use the aufs tools ! Only in rare occasions that you need to use the aufs utils or tools.

If you compile from latest sourceforge version from the developer, it is surely OK. My concern was about the "correct" version of aufs.

"Essential" is of course a relative concept. As a new example, on Friday an error message appeared on R-help: http://www.mail-archive.com/[email protected]
A possible explanation, mentioned by Brian Ripley, is Debian's versions of the lapack and blas libraries. When Debian is used on a scientific/engineering workstation, those libraries are surely essential, even though the vast majority of users don't use them. They could, however, crop up anywhere, embedded in image processing routines, games etc.

A more actual example is provided by this thread: Use of aufs-tools to make no-wear Knoppix versions for flash memory. With widespread use, those tools could migrate into the "essential" category, I think.

Whatever it is, the point I want to make is that, I am pretty confident that Klaus K have compiled aufs correctly to match his version of kernel. The last thing to suspect is the version of kernel aufs module is wrong. Knoppix will not run if the kernel aufs module is wrong.

The aufs toolset is a totally different story. Knoppix does not use it. Most debian users also do not use it. So I am not surprised that it might be faulty.
