For example, if you specify username ogden, the installation process will automatically create group ogden and add user ogden to group ogden.

You can select gnome in addition to (or instead of) kde. These two packages are competing implementations of an X windows-based desktop environment. You need at least one of them. Experienced Linux users often have strong preferences for one or the other package. We had no strong preferences and arbitrarily selected kde; we have been quite satisfied with this choice. (We also used gnome on other installations, with no problems.)

9FLEX-ES needs to use TCP/IP port 24 on Linux for its Terminal Solicitor function. Almost all FLEX-ES installations will require this. FLEX-ES will also use port 555 if you have remote FLEX-ES resources installed. The typical ThinkPad/EFS user will probably not use this, especially for initial FLEX-ES use. If you install firewall functions, be certain that port 24 is not blocked.
