Good point.

Moving things in and out to some "unmaintained" directory… I am not sure 
about that either. I tend to think that moving code around does not 
solve the underlying issue.

Which, according to what I got from Matthew, was that distributors 
enable just about every filesystem they can enable which lead to hfs 
being used for automounting an USB stick formatted with it.

In the end what may be beneficial would be hinting distributors and 
people who compile their own kernels at what features are considered 
stable, secure and well tested and what features are not, but how to 
determine that? The hint could be some kernel option flag that would be 
displayed by make *config. But then it probably needs also a 
justification or at least a link to more information.

Actually did ever someone audit the whole kernel source?

Thanks,
