Well, as far as I know, the FreeBSD project is funding people doing a
certain work! So, the implied opposit, FreeBSD is developed "free" isn't
true.

What I am in this terminology? I can hardly write some scientific code
for my science, I'm able to patch software a bit, that has been
developed only for Linux these days (ISIS3 from the USGS, for instance,
but I do not dare to publish the crap of port I produced since it is not
"professional"). I'm with FreeBSD now since 1996/97. I'm still with the
system, although I desperately need scientific grade compilers or GPGPU
support. So, even if Linux offers me a really much more convenient way
to do my work, I stayed with FreeBSD since there is no real alternative
in terms of cleaness of the system. I have also to administer an Ubuntu
and Suse server and I feel not amused by this script hell that covers
the real system just to get kiddies or Windows-Admins into the
"admin-position".

And, I dare to put some critics herein! Since I see that FreeBSD is
"free", why not trying to make it better and more towards perfect?

This is nonesense, you know that, regarding to my case.

Well, in real world and beyond this armchair polemics, managers at last
do the decissions. Those people dropping math, physics, with no glue to
how things work in nature get a degree in law, business and whatsowever
and then decide. In my eyes, those are enemies of every development and
progress, but this is polemics, too. I faced this many times and it is
hard to convince those people not taking care of knobs.
But as an admin myself, I need to know about knobs and if essential
knobs are not documented, than there is a potential gone for the OS in
question. Look at FreeBSD and the problem of how well sysctls and their
working are documented. It needs to be fixed.

Yes, everyone interseted in this thread and communicating is aware of
that fact.
