# Set up PATH depending on whether we're root or a normal user.
# There's no real reason to exclude sbin paths from the normal user,
# but it can make tab-completion easier when they aren't in the
# user's PATH to pollute the executable namespace.
#
# It is intentional in the following line to use || instead of -o.
# This way the evaluation can be short-circuited and calling whoami is
# avoided.
