Nail on the head.

What you just described is the difference between a System Administrator
a System Integrator and a Programmer.

An integrator can spot a square wheel and make it (mostly) round again.
Typically, an integrator can also at least 'get by' with
Bash/Perl/C/Python and to a large extent even PHP.

An 'admin' if fresh out of the RHCE pool can install pre-packed stuff
and configure it. As they build experience they (ideally) begin building
from source, learning a bit of programming, writing some scripts, etc.

A programmer made the wheel to begin with, but unless the programmer was
an integrator, you probably need an integrator to compensate for the
programmer assuming an 'ideal world', or how the round wheel got square
to begin with. 

Likewise, you don't want to pay an integrator to sit around playing
Tetris waiting for services to fail.

Most regulars on this list are integrators, so he did put the question
to the right place.

Bah let them keep proving just how much a paper certificate is worth.
The only thing that makes one integrator any more or less competent than
the next is their methodology.

An admin is just developing a methodology, or (sadly) doesn't see the
need to since all he does is call RHEL support.

I think, at the least in any interview or consulting that you do, you
should point out that you are a system *integrator* , and the
difference, to help stop this stupid 'sysadmin' misconception.

If it keeps up, you'll refer to someone 'sysadmining' your server like
you would refer to someone 'hacking' your PayPal account.

We aren't going to stop nincompoops from calling themselves admins, so
we may as well call ourselves something else to show the difference :)
