The user ID S10GOLD, is created with the following directory definition. This ID should never
logged on to, so the password is set to NOLOG. The minidisks 11Bx are the read-write gold
disks and 21Bx are the read-only gold disks. It requires the space of a complete 3390-9
because it stores two systems.

The minidisk layout is verified and the changes are brought online, either via the DIRECTXA
command, or via the appropriate “add” command if you are using a directory maintenance
product.
Allowing access to the system VSWITCH
The S10RWMNT, S10RWTST, S10ROGLD and LNXCLONE user IDs are given access to system’s
VSWITCH. The S10GOLD user ID does not need access to the VSWITCH as no Linux system
will ever be IPLed from it. The following statements are put in AUTOLOG1’s PROFILE EXEC:
'cp set vswitch vsw1 grant s10rwmnt'
'cp set vswitch vsw1 grant s10rwtst'
'cp set vswitch vsw1 grant s10rogld'
'cp set vswitch vsw1 grant lnxclone'
These commands are also run interactively from the command line for the current z/VM
session.
1.5.2 Downloading the associated tar file
The tar file associated with this paper is available at:
http://linuxvm.org/present/misc/ro-root-S10.tgz
It is downloaded to a Linux, UNIX or Windows machine and untarred. The z/VM files are
needed before the first Linux system is installed. Later, the tar file is copied to the Linux
worker system running on LNXCLONE.
The command to untar the file from a Linux or UNIX system is as follows, assuming the tar file
has been downloaded to /tmp/:
# cd /tmp
# tar xzvf ro-root-S10.tgz
