All, Jim Sibley has contributed a HOWTO titled "mkinitrd and cloning notes for SUSE SLES8 and Red Hat EL3 AS on zSeries." The introduction states: "SUSE Linux Enterprise Server 8 (SLES8) and Red Hat Enterprise Linux 3 (RHEL3) both use an initial ramdisk (initrd) during the boot process to include the device driver modules. This allows them to have a single script for all platforms to include all the necessary drivers for each platform and adds more flexibility in adding device drivers without having to recompile the kernel. This has several implications for the zSeries (i.e., s/390 or zSeries) Linux system administrator."
