System configuration management utility to alter system personality
This script provides functionality for manipulating collections of configuration files which can be organised so as to alter the personality of a system.
Initially, the “base” personality is established. This personality contains the “reference” copies of configuration files, and is used when creating new personalities. The files which are currently considered part of the system’s personality are those contained in the base personality.
A new personality is established by making a copy of the base personality under a new name. Each personality maintains a separate copy of all configuration files under /etc/personality.
To install a new personality, the files currently in place are saved back to the current personality as indicated in /etc/personality/current, and the files for the new personality copied into place. The ‘select’ and ‘menu’ commands which perform these installations are implemented in such a fashion as to only require the tools available on the root filesystem, so that they may be invoked at the earliest stage during system startup.
