I'll ignore the fact that project goals have nothing to do with
waterfall or agile, and ask, what are your short-term goals?

Why is this an "official" Gentoo project without this being discussed in
an open manner?

Given that the Gentoo Foundation is claiming copyright on this project
now, not announcing it seems a bit rude to the rest of us who make up
this foundation, don't you think?

That's not very open :(

You do realize that you didn't really drop the dependency at all, right?

Huh?  Really?  It's as if you think we all are just throwing stuff
against the wall and seeing what sticks?  We aren't responding to real
users, customers, research, history, and competitors?  Your dismissal of
the people who create the system you are using seems pretty bold.

Ok, what is that structure you are wishing were present?  What problems
do you have with systemd on a technical level that are not being
addressed?  What technical problems with udev do you have that caused
this to be forked?  What problems are you wishing to solve, and what
goals do you have by doing all of this?

Have you studied the problem area for booting, process monitoring,
system isolation, device creation and notification, persistant naming,
multiple users with multiple displays, and the like, and found that
Linux is lacking in this area?  If so, I would love to learn more, as I
want Linux, and Gentoo, to succeed.  Without knowing the problems you
are having, there's no way anyone will ever change.
