Let me add the difficulty of learning to google for problem
identification and solution, rather than using IBM manuals (item one)
and (item two) figuring out how to set up a gui interface.  Most Linux
classes teach gui sysadmin interfaces. The teacher looks at you funny
when you continue to ask about command line alternatives.  :-)

Subject: Re: Mini-survey: Linux usability

Peter, 

Responding on list, because I think public discussion is probably useful
on this topic.

The two areas that get the most blowback from the people we deal with
are: 

1) The contortions necessary to get the first guest installed,
particularly for a traditional mainframe population. Having to use
non-mainframe tools or obscure devices such as the HMC CD or DVD drive
(which are usually not physically accessible, or not managed by operator
automation in a way that is convenient to people doing the installs). 

We (SNA) are well advanced on doing something about that, but that's the
biggest complaint we hear.

2) The difficulty of working with the console in environments with
security regimins which require root logins to be limited to the console
device for Linux systems.

Most sites with Unix or Linux/Intel backgrounds and any concern for
security have security standards for managing privileged access to
systems. Complying with those standards -- to play along with the
message of "Linux is Linux" -- means disabling root logins on all
terminals but the console...but that puts Unix admins in the position of
having no fullscreen access to do repairs, and the current generation
has no experience with TTY consoles. 
The VT220 hardware console support is nice, but few have it yet, and
won't be available widely until 5.3 becomes ubiquitous (and there's no
direct support in the VM TCP stack for a solicitor to connect to a
virtualized console).

Everything. I'm very generalized...8-)
