This section discusses renaming the default configuration files groups used by the UPDATE and INSTALL utilities mentioned in Chapter 3 “System Startup Functions”.
Overview |
 |
The INSTALL utility replaces a system's configuration files with a default configuration. These defaults allow the system manager or system operator to boot the system to a fully operational level. They may then alter the functioning configuration to meet their system's needs.
The UPDATE utility optionally replaces a system's configuration files with defaults. During an update, the system manager or system operator has the choice of whether or not to use a configuration stored on the system volume or to replace the current configuration with the default.
Before a system can properly use its START command, a functioning set of configuration files must reside in the configuration group CONFIG. The START command uses CONFIG as its default configuration group.
Since multiple configuration groups reside on a system load tape (SLT), CONFIG is empty until the system manager copies an appropriate configuration group into it.
