Have you tried "man su" yet? Because I think everyone expects you to
do that. Before we devolve into utter flaming madness, please?
Flareon
Of course! I've looked at lots of man pages.
Now please instruct me as to what, exactly, in the su man page answers
my original question.
Also please expound on why the LFS book says to use "su - lfs" when the
su man page says this:
"It is recommended to always use the --login option (instead its
shortcut -) to avoid side effects caused by mixing environments."
