When installing a clone system with a Solaris Flash differential archive, you can use the no_content_check keyword to ignore file-by-file validation. File-by-file validation ensures that the clone system is a duplicate of the master system. Avoid using this keyword unless you are sure the clone system is a duplicate of the original master system.
If you use no_content_check, all new files are deleted to bring the clone system to the expected state. If you are not certain that you want files deleted, use the default, which protects new files by stopping the installation.
