Customizing the cron, uucp, and mail utilities

This topic contains steps that are needed to set up the cron, uucp, and mail utilities for read-only file systems. See z/OS UNIX System Services Command Reference for additional customization instructions for configuring these utilities.

The instructions work for most customer environments. Customers with different customized environments should use this information as a basis to make their respective changes. The instructions are based on the following assumptions:
  • The target system was IPLed in your test environment, the root file system data set is mounted on / (slash = the root) in read/write mode
  • The /var file system is mounted on the /var mount point in read/write mode
  • File systems such as the sysplex root and the system-specific file systems are not being used or being mounted while the customization is taking place.
