But there's no real reason to make it a linux-booting CD;
even a Windows setup (as the existing TurnKey CD has) would
be adequate (and provides the configuration files/scripting
for a linux-launched equivalent, too).
So it'd be a simple setup w/ DASD images (perhaps an install
tape image?) in CCKD w/ shadowing possible would not hurt.
If DVD images (being 4.7GB in size) can be tolerated given
the number of such drives becoming "standard" then a much
larger set of installed images becomes possible.
So it'd be set up for mainframe-ignorant folks like me that
want to be able to work with and learn the environment.
If there was a way to get IBM to let us sneak on copies of
the various redbooks that would be nice too.
The use of a turnkey tool, especially if it supports the
Linux development environment, is that it provides an initial
portation tool. (I'm not naive enough to think that it'd do
the *whole* job since you'd want to make sure it worked on
the real metal of a mainframe at some point.)
So, we're talking a CD that has the Hercules emulator on it
(with an x86 linux tree as well) made to autostart in the
Windows environment with all the neat-and-keen tools that
the MVS 3.8 Tur(n)Key used to show the way.
The a floppy resident linux + hercules mechanism seems a
little bit, well, tight.
(Imagining banks of 100 MB ZIP drives emulating 3330s...)
