If you need to su to root, the textbook-correct way of doing it on the
command line is this:
/bin/su -
(note the minus sign, it is very important. The full pathname is recommended
for safety: it makes sure you are running the correct "su" and not something
else by mistake).
If you leave out the minus sign, environment variables won't be reset to the
required ones for that user (root in this case), the user login
profiles/scripts won't be run, and not everything will work correctly.
