ZOSMIGV1R13_RO

Description:

Before z/OS® V1R13, certain post-installation activities had to be done for each new release for the cron, mail, and uucp utilities in order for the root file system to be mounted read-only. Starting in z/OS V1R13, the /usr/lib/cron, /usr/mail, and /usr/spool directories are provided as symbolic links. On z/OS V1R11 and z/OS V1R12 this check will indicate whether you will be affected by this migration action in z/OS V1R13.
