i am not in disagreement with this as i used *unix* in it's early form. my early unix
manuals are buried too deep to get to, so i can not quote from them or find when
change came about.
but this is not *unix*, we are discussing *linux*. in *linux*, the command 'su' is
'substitute user or group'.
in *linux*, 'su' gives a user who knows 'root' password, ability to become _any_user_
or a member of _any_group_. therefore, i again say, command 'su' is not 'super user'.
so if i give command 'su poc' or 'su paul', i do not become a 'superuser'. i simply
become user 'poc' or user 'paul'.

*msdos* systems and *ms windows* have very little concept of anything.
in a free world without fences, who needs gates.
help microsoft stamp out piracy - give linux to a friend today
to mess up a linux box, you need to work at it;
to mess up an ms windows box, you just need to *look at* it.
