Mark:
Let me ask you a question concerning the
administrative/management/monitoring tasks on zLinux and how they relate
to the job of the operator, performance tuner and systems programmer in
a mainframe environment, such as z/OS.
I kind of get the feel that root in zLinux is kind of the equivalent of
the mainframe operator (although I see it has the capabilities of
adduser and passwd setting for user), which smack a bit of systems
programmer, security administrator and even help desk in the mainframe
world.
It seems that a zLinux user given superuser capabilities would be more
like the system programmer (installing products, debugging the system
and applying maintenance) and a user trained in handling specific
monitoring tools might act as performance analyst and tuner.
Is this approximately correct? Or, how do these functions get doled out
and managed in the zLinux world?

I guess the best strategy is to get them some experience with Ubuntu or
an equivalent distro (in what I'll call "mixed mode" - using both
commands and a GUI) and then show zLinux to the server folks when I get
it going.
It might be better in the short term if you introduced them to the same distribution as
they will wind up running on the mainframe. I've supported quite a few different Linux
versions without a whole lot of adjustment effort, but for the newcomer that might be too
much of a learning curve. For the "big commercially supported" options, that
leaves SLES and RHEL, although Debian/390 and Slack/390 are also supported by third
parties. There are also Gentoo, Fedora, and CentOS, but I'm not personally aware of
anyone that offers support for them.
