This is correct.

Yes, this is correct. I read the log over several times and it isn't
clear what the council actually voted on. Tony, it seems clear that you want to
mandate that gentoo in its default configuration will support separate
/usr without an initramfs. The thing that isn't clear is whether the
rest of the council wants to do that. In reading the log, there was
definite uncertainty about whether the vote was just to continue
supporting /usr as a separate configuration or to mandate how
separate /usr was going to be supported in the default configuration.

Rich, you are absolutely right. There is not an argument anywhere about
whether separate /usr is supported.

 I'm not excited about parts of the vertical integration either. Newer
 versions of gnome are going to start requiring systemd from what I've
 heard, and I disagree with that level of integration.

Agreed.
