So root is lost - can someone help me tell it how to 'phone home'? I was
wondering why I was getting the strange 'sh-3.00#' prompt in the third

and 5 are my clue, but I don't how to fix this, or for that matter, how
it got into this state.
"su" only changes the process' effective UID, but doesn't give you
root's environment. "su -" DOES give you root's environment (including
root's path and, yes, $HOME). It's equivalent to logging in as root.
Assuming I understood you correctly, I tried this:
sh-3.00# su cj
[cj@viewridgeproductions2 misc]$ su root
Password:
sh-3.00# kcontrol
Aborting. $HOME is not set.
sh-3.00#
I'm getting the same bad result, if I follow you right.
The command is
su -
(ess-you-blank-dash). If no username is used after the dash, root is
assumed. The dash option makes "su" perform the same things that a
login would. For an example:
$ su cj
makes your effective UID that of user "cj", but you retain YOUR
environment, current directory, etc., while
$ su - cj
would make your effective UID that of user "cj" AND give you cj's full
environment. You're also transferred to cj's home directory (which
is how $HOME gets set anyway).
