[mdlug] /etc/sudoers -A rant and an attempt at better documentation

[Raymond McLaughlin]

LUG nuts:

It is often bandied about that using 'sudo' is a good way to avoid
having to login as root, for example, and for giving certain users
greater privilege *for certain commands*. A little looking into this
wonderful command quickly reveals that to use 'sudo' to dole out
privileges effectively an administrator must edit the /etc/sudoers file,
and therein lies the rub. The manual page for the sudoers file.

<rant>
It may be that I'm just dense, but I find the man page 'man sudoers' to
be the most insanely, obscenely incomprehensible excuse for
documentation that I can recall ever encountering. I don't want to sound
ungrateful to the programmers who wrote this, no doubt excellent
program, but the man page is a quintessential example of documentation
written by programmers for the benefit of people who already know the
answers.
