The Solaris superuser (root) has been replaced by the Trusted Solaris root role. For the Trusted Solaris SSP 3.1.1 and the Trusted Solaris AP 2.2, any commands that superuser runs in a Solaris environment are run by the root role in a Trusted Solaris environment. The root role runs with the profile shell (pfsh), and should not be changed to run with other shells.
