Now comes the main question:
-----------
Is there a way I can now take this installed system and create an
installation disk with a text-based installer?
In other words, I'd like to keep all the software I installed, removed
and configured during the entire process, and must also include the
customized user permissions.
-----------
I say text-based installer since I would be creating a customized
preseed that would install the distro with little user intervention.
This is required since this would have to be installed on a number of
such thin-clients.
