Yep I understood all that and the reasoning behind it. The only thing I
was trying to say was that while documenting it in the release notes is
a nice and necessary step, if there are other channels to let folks know
about this, like say an e-mail list, it might be worthwhile as well.
This is just a suggestion.

Not all folks read the release notes, which of course they all should,
and this change can lead to some rather surprising results for those of
us who ended up with guest_u by default.

As I said I just got lucky in some ways by running Fedora 18 against my
IPA servers I was able to only cause issues for myself.
