This is an installation kit for linux based X terminal.
This kit use a RedHat 5.0, 5.1, 5.2, 6.0 or 6.1 cdrom and install a set of packages in /xterminals/root. It installs around 90 megs of stuff. See the end of this document for RedHat 6.0 details.
All X terminals are sharing this /xterminals/root. Further, this is read-only. No X terminal needs to write there, even when configuring a new terminal.
This kit may be installed on almost any distribution that can run the rpm command. The fact that the X terminal will run some parts of redhat 5.x does not affect the operation of the server itself. This kit has been installed on a redhat 5.0 server and a redhat 4.2 server. So I guess it will work on SuSE and Caldera, and probaly anything.
