Seconded for -CURRENT. I think, we should at least provide some brief
document, whatsoever on incompatibilities with the sort implementation that
is currently active in RELENG_9, no matter how buggy it is.

This allows adopters and people, who have to migrate their production systems
to identify and quantify the areas to change and perform some risk management.
This also allows them to move more quickly to the new release, since they
can start with the necessary changes earlier and plan ahead.

We provide such changes usually in the release notes for various tools, we
updated and I think that giving out such a document earlier will be extremely
benefitial for companies, which have to deal with more than one or two
servers running FreeBSD, especially if we know that the currently shipped
implementation is buggy and people most likely will have their own workarounds
for that.

Cheers
Marcus
