Root is "UNIX god". Like a a z/OS sysprog being a RACF administrator as well. And more. If you use Ubuntu, you realize that they discourse actually logging on as root. Instead, they use "sudo". In a real Linux environment, I would likely set up security groups in sudo so that some people can do the sysprog like functions (yum, apt, rpm and so on), some could do security (useradd, usermod, userdel) and so on. > > It seems that a zLinux user given superuser capabilities would be more > like the system programmer (installing products, debugging the system > and applying maintenance) and a user trained in handling specific > monitoring tools might act as performance analyst and tuner. > > Is this approximately correct?
