22 Sharing and maintaining SLES 10 SP2 Linux under z/VM
The LINK statement to the CMSCLONE 192 disk enables the other user IDs to share a common
read-only 191 disk:

A user ID LNXCLONE is created with the following directory definition. A minimal Linux image
will be installed onto the 1B0 disk so the mnt2rogld.sh script can be run from
/usr/local/sbin/. Note the privilege class B is added so FLASHCOPY can be invoked, and
the option LNKNOPAS is included so that all minidisks can be linked with no password.

The user ID S10RWMNT is created. The first Linux image is installed into this ID. Refer to
Table 1-1 on page 16 to see which minidisks are for which file systems. This definition utilizes
half of a 3390-9 (5008 cylinders) for all disks. You may want to use more disk space for each
read-write Linux system or you may want to implement logical volumes on some file systems,
such as /var/, to allow for growth. Logical volumes have not been implemented in this paper,
but there is a brief discussion on the topic in the section 1.9.1, “Utilizing logical volumes” on
page 65.
Following is the directory definition for the user ID S10RWMNT:
