Not to mention hundreds or thousands of those same mainframes that run
the descendants of OS/360 and now also run Linux, either natively or in

As an aside: Somewhat contrary to the origina post, the Linux man page
for su may be a bit above average, but covers su pretty well, including
the use of the '-' or '-l' or '--login' options.
