It's all important.
What is administration, anyway? It's making the machine do whatever it
is its owners need it to do. You may not need to know the details of
applications (though that may not be the case always) but you certainly
have to know how the apps being used affect the OS and the hardware and
vice-versa. An administrator may not be a "performance expert" or a
"storage expert" or an "* expert", but you do need familiarity with all
those things. And because Windows boxen will undoubtedly be in the mix,
you need at least some knowledge of that crapola also (pardon my
prejudice - does it show?).
An administrator, then, is a generalist. Unless you know ahead of time
that you will be working for XYZ and their environment consists of a, b
and d, you can't afford to spend too much time learning too many
details. I don't mean to imply that superficiality is your goal, but
you have to balance depth against breadth and realize that
administrators usually need breadth more than depth. It's a tough act
sometimes - I know I constantly find myself learning more than I really
wanted to know about Y and wishing I had the time to really dig into Z.
One thing you might find useful is my Linux Skills Tests at
http://aplawrence.com/Tests/Linux . I originally developed these for
testing tech job applicants - I'd sit down with the person and have them
verbally answer a few dozen questions like this.. it gave me a real good
idea of how broad their skills were (tech folk need perhaps even broader
skills than admins).. anyway, it might help show you where your weak
areas are. Some of the questions are very basic, some aren't, but if
you find yourself really thrown by a lot of them, you need a lot of
work. Most of the people who answer questions here would likely waltz
through them and quit out of boredom rather soon - if that's your
experience, you are probably well prepared to be an admin. And if not..
well, learning just takes time and effort, right?
