The biggest problem with Red Hat on the mainframe is that it's a minority product.
Most Linux users on zSeries use SUSE, and most products for Linux on zSeries are for

There's another possibility: format the DASD from CMS using the LXFMT program.

up for z/VM. All of the others are ports from z/OS. RACF tries to fit z/OS
