Good point.

Moving things in and out to some "unmaintained" directoryâ 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?
