In addition to Jim C.'s suggestions, you can also start an interactive
shell via su (or sudo) and then use the built-in "suspend" command to
go back to the non-root shell from which it was invoked. Then you can
re-enter it using the usual job-control commands. The shell will only
honor a "suspend" command when it's not a login shell, so you don't
have to worry about suspending a shell with no other shell "above" it
to handle the suspended process state.

I find using screen even more comfortable. You can easily have several
sessions open and switch between them and keep being logged in as
root. It works well with SSH access too.

Alright, looks like I have to add a few tools to my tool box. With
regard to screen, what advantages does it have over running konsole with
multiple sessions? I've looked at the man page, but can't figure out
what the advantage would be over multiple tabs in konsole and using
shift+rt or shift+lt arrows to move between screens. Marcin, what are
your thoughts?

The beauty of screen is that you can open a session in a konsole window on
your desktop at work, and then from home ssh to your work PC, and detatch the
screen session from your work desktop and have it appear on your home konsole
window. Then the next morning, you can go to a client's office and move the
screen view to the konsole window on your laptop. All this without
interrupting in any way the shell, or vi session, or mysql session, or
whatever you had running when you created the screen session at the office.

You can have multiple screen sessions open on a single konsole window, one
visible at a time. You can even open a screen session on a virtual console
of a machine not running X at all, and then view that session inside a KDE
konsole from some arbitrary remote system (provided you can get in, say with
ssh).

This just scratches the surface, and I know there's lots about screen I've
never even tried or know exists.
