Issue/Introduction

How to enable Auto Creation of Home Directories:

The only mechanism that will create a Home directory when OMVS is entered is the Automount facility.

If you will have a number of new users, then you could set up Automount and use a different path for their HOME directories ( e.g. /home ) instead of /u .

Then Automount will dynamically create a separate ZFS for each user and create a mount point of /home/userid and mount the ZFS for you.
