If, following a shutdown in a system having the same version, a startup takes place in the system having the same version with a cold start, a warm start, a SELECTIVE start or a ZIP start, then the distribution of privileges is the same as prior to the last shutdown.
If the file SYSSRPM is not available or has been irreparably destroyed, a startup is possible only after the user catalog is either restored, reset or created again. In a restore user catalog the assignment of privileges is the same as at the time of the backup. In a newly created or reset user catalog the assignment of privileges is performed as in the case of first startup.
Information concerning the backup and reconstruction of the user catalog may be found in the “Introduction to System Administration” [2].
