The need for an all-Privileged user
Although this mechanism allows you to avoid giving users the power
to act as superuser, sometimes it is still necessary for a user to
act as the all-powerful superuser, such as when diagnosing system
problems, or cleaning up after a system crash. To support this,
the current privilege mechanism still recognizes a process with a
UID of 0 as possessing all of the defined discrete
privileges. In effect, the root user is still superuser.
