Re: commands as super-user

You lose a layer of security auditing, but make the user's life much

With respect: bosh.  Root login is the ultimate evil.  On a multiuser
system you can't tell which root did what.

But sudo is important on a single-user system because:

1)  "su -c" can introduct some fancy shell quoting requirements.
    Don't peek and tell me where the 'su -c "mkdir ${HOME}/foo"'
    command makes a directory.  Not novice-friendly.

2)  there is no record of what was done by the "su -c" command and
    this makes error recovery more difficult.  I know what I *meant*
    to type, but what did I *actually* type?

3)  Easier to learn the correct habit than unlearn a bad one later.

A single paragraph / appendix what boils down to:

   # echo "${USER} ALL=(ALL) NOPASSWD: ALL" >>/etc/sudoers

doesn't seem too onerous.

All your concerns are based on the fact every user of a multiuser Linux has the root password. This is only the case when there is just one user. So a plain user can try su c but it will not work.
