Checking modifications to configuration files
The geninstall command provides an easy way to see what modifications have been made to the configuration files listed in /etc/check_config.files.
When these files have been changed during a geninstall installation
or update operation, the differences between the old and new files is recorded
in the /var/adm/ras/config.diff file. If /etc/check_config.files requests
that the old file be saved, the old file can be found in the /var/adm/config directory.
The /etc/check_config.files file can be edited and used
to specify whether old configuration files that have been changed should be
saved (indicated by
s) or deleted (indicated by d),
and has the following format:d /etc/inittab
