I've done a lot of 'lite' sysadmin in my time, but it was way back in
the Unix days on SunOS and even before that. I actually used to have
that book, as well as the 'Devil' book. But I've moved many times, and
got rid of all my books as I was googling everything anyway. I have
worked with many really great sysadmins in my time, and I know how
valuable they are. So I would never pass myself off as one.

A client of mine (who will remain nameless), has a client (who will
also remain nameless), and they are so concerned about corporate
espionage and loss of trade secrets, they do no permit any remote
access to their systems. They site is so locked down, you cannot bring
in any device of any kind.
