There are lots of rumors regarding the existence of a GUI.
Sometimes it's a bit weird to use very low level tools when you have 
tools that will give you much more power in your hands.

But again some prefer to know what they do in the lowest levels and 
others just want to do the thing while they know it works and was 
designed to work.
When the two collide ( works vs power) lots prefer to have only works 
(what seems to be a very bad assumption).

Many times you don't need GUI for servers to operate and sometimes the 
existence of a GUI slow the server down and lowering the performance of 
the system.

So taking couple things into account most admins agree that a GUI should 
not be needed when you know how to operate the machine using the CLI tools.
If you feel the need to use GUI tools have it your way and have a nice 
smile to your CLI friends which struggle every once in a while how to do 
things in a way they prefer and note that not all admins are alike.

(I am still looking for a GUI utils to operate GlusterFS which seems to 
be there in RH storage systems)
