chris you can just copy the whole install and use it under a different
session name. But maybe more to what you are trying to do and not sure
that it would work is that you can copy your install.log, settings
local and win.log to a new install session and making sure that you
change the specified pointers within those files which point to the
old session name to the new session name. Don't know for sure, haven't
tried that.
However with console it's pretty easy to setup your new installation
if you aren't just going to copy it and use it as a separate session.
