This sentence really stood out for me, and implies a profound lack of
understanding of multi-user machines. No offense intended.
I've been a Unix admin for over ten years, and I like to think that I
know my way around pretty well. But I do not and will NEVER log in to a
machine as root to do work. I am the only user of my MacOS X laptop and
home Linux boxes, and I still have my own personal login on all of
them. What's at issue is not ownership or trust, but one of
accountability and safety.
Any OS worth its weight in silicon will make a distinction between
blessed and unblessed users. It can be phrased in different ways --
root vs. non-root, admin vs. non-admin. But no one should EVER log in
to a machine as root. Period. (1)
Multi-user/modern operating systems exist precisely to destroy the fatal
flaw that you are attempting to reintroduce. Users should have reduced
privileges during normal use, and conditional privilege on demand. Safe
from User Error and no less functional on GUI-based systems.
People keep saying this, but I'll say it again. This can easily be done
in user-space. This HAS been done. Many times. Well. It's possible
to put a user in privileged mode automatically, but I'm not convinced
that an extra prompt to go into privileged mode is a bad thing from a
So it doesn't need to be in the kernel. And why put it there if it
doesn't need to be? Even if it's off by default, it's bloat. And
dangerous, conceptually flawed bloat that can't be disabled with
'chkconfig' or 'rpm -e'. And how many people will use it? And should
the kernel group allow them to from an out-of-box kernel? As I
understand it, part of the responsibility of the maintainers is to
maintain a conceptually focused kernel. There's nothing preventing you
from distributing your patch, but inserting this into "the" kernel seems
I think we understand the "why" of your patch, but I think you need to
elucidate further on how the ends justify the means.
