Re: F10 and no root login - impossible to maintain systems!

The chief compelling one he mentions seems to be when NFS goes down
and Linux can't find the /home partition.

Or, to put it bluntly, when the Linux distribution isn't smart enough
to protect "non-technical users" (an admittedly subjective term) from
technical problems.  Which is often.

But your critique, Mr. Sundaram, doesn't seem to imply that people
shouldn't login as root -- merely that you disagree with allowing them
to open a root session in X.  To be rhetorical, we must ask, why?
After all, there's no such thing as "partial root power" -- you either
have full root privileges in a terminal in a normal user X session, or
full root privileges in a root X session.

Here's the why:  you feel that a root X session is too insecure --
which it may indeed be.  So we believe that the "ideal" method is to
not allow X root logins.  But keep in mind, this is not actually an
ideal.  It's a kludge to go around the fact that X is designed rather
horribly from a security standpoint.  The "user session only" method
allows you to work around that.

But in the above case, user-session-X goes down.  You say login at
runlevel 3.  But let's face it, many users comfortable with Linux
still aren't at the "I roll my own shell-scripts" stage -- they still
work in GUI mentalities, and odds are, even if they can roll their own
shell-scripts, they won't understand how to fix administrative errors
as well as if they use the actual GUI administrative tools.

For most users, the GUI is critical for maintaining their system.  So
it is critical that the GUI be not allowed to fail.

Hence, leave the root-session-X backdoor open, (perhaps with a catch
-- for example, network functionality is disabled in root-session-X --
so that the only possible errors can come from user error, rather than
security vulnerabilities.  how about that?) or come up with another
solution.  "No GUI" for the sake of safety is a no-go solution for
many people.
