18.2.4. Installation Phase 3
- Graphical mode
This can be used through a VNC client (recommended) or through an X11 server. You can use your mouse and keyboard to navigate through the screens, click buttons, and enter text in fields.
- Text-based mode
This interface does not offer all interface elements of the GUI and does not support all settings. Use this for interactive installations if you cannot use a VNC client or X11 server.
- cmdline mode
This is intended for automated installations on System z. (Refer to Section 26.6, “Parameters for Kickstart Installations”)
display= variable in the parameter file (refer to Section 26.4, “VNC and X11 Parameters” for details). In Red Hat Enterprise Linux 6.9 the text-based installation has been reduced to minimize user interaction. Features like installation on FCP-attached SCSI devices, changing partition layout, or package selection are only available with the graphical user interface installation. Use the graphical installation whenever possible. (Refer to Chapter 23, Installation Phase 3: Installing Using Anaconda.)
