I'd love to see more intercommunication -- Tresys had contacted me about
getting involved in SELinux for Ubuntu, and we were happy to get some
help.  Since getting it to play nice with Upstart and AppArmor needed some
work, no one had yet stepped up to do anything for SELinux in Ubuntu and as
a result SELinux had been virtually unusable there.

I did try to point them your way -- I don't like seeing a delta from
Debian.  I think timing was just off; they wanted newer revisions of
things than what was in unstable when they started their work a few
months back.

I don't think this was malicious -- I think they just figured it would
be easier for them to manage future updates in Ubuntu if they used
different packaging.  But I'm just guessing -- I did balk a bit at the
extensive changes, but again, no one else was working on SELinux in
Ubuntu, so we welcomed it.

Again, it's just bad timing -- Ubuntu's feature freeze had been
coming up, so they worked with what they could.  The majority of the
integration work needed for Ubuntu code-wise is upstream now, and the
bulk boot-time packaging bits is limited to the Ubuntu-only "selinux"
package they created.

Anyway, I just wanted to give some background history for all of this.
I don't want to suggest anyone should take anyone else's packaging.  :)
