I never met a sysadmin that was anything like the bofh.
Look, it is a funny story, nothing more.
Just like there is dilbert and other stuff.
Do I want to become a bofh? NO
Do I like a complete Fantasy story in which a sysadmin runs amok?
Yes, yes I do.
I would never compare that to reality, just as I wouldn't expect that lord of the rings is a accurate history documentation and that star wars a prophecy.
To your other points:
I rarely met toxic people and when I did it was one of the following reasons:
* As soon as a system was down(Of course, no money for HA or preemptive maintenance) users called and screamed(Yes screamed)
at the it people till one of them had enough and screamed back.
* The Sysadmin was responsible for all the systems 24/7 but got paid 40 hours.
* The sysadmin had to repeateadly explain to a user how to change his or her password and how to login to computer.
* Sysadmin got the blame for not backing up a system becaus some enduser deployed in on their smuggled in nas
You will see that most people that become toxic, suprise suprise, are in a toxic environment.
Just to iterate over your last point:
The Job of a sysadmin is to build and deply systems, keep them running, document and plan new things.
It is NOT the job of a sysadmin to help people learn how to use software, which they should know about because they knew they had to use it, when they applied for the job. That IS helpdesk work.
E.g. "The software writes I can't connect to the server" is a valid question.
"I don't know how to make a paragraph bold in word" is not valid.
Because that would mean that you just hired a person who has no idea on how do to his job. How to you expect a sysadmin to know every programm inside out?
Heck I know how to deploy photoshop, butI have no clue how do to anything in it and I frankly don't care.
