The audit configuration files in Oracle Solaris are marked in the package with the preserve=renamenew package attribute. This attribute preserves any modifications you make to the files across updates. For information about the effects of the preserve values, see the pkg(5) man page.
These configuration files are also marked with the overlay=allow package attribute. This attribute enables you to create your own package that contains these files and replace the Oracle Solaris files with files from your package. When you set the overlay attribute to true in your package, the pkg subcommands, such as verify, fix, revert, and so on, will return results on your packages. For more information, see the pkg(1) and pkg(5) man pages.
