PROFILE EXEC. Also, an XAUTOLOG statement is added so that the RH6GOLD user ID is
automatically logged on at z/VM IPL time. To do this, perform the following steps:
► Link and access the AUTOLOG1 191 disk read/write and edit the file PROFILE EXEC. Add the
RH6GOLD user ID to the section that grants access to the VSWITCH. Note that you don’t
want to add RH6GOLD to the XAUTOLOG section, as this Linux user ID will not normally be
logged on:
==> link autolog1 191 1191 mr
==> acc 1191 f
==> x profile exec f // add two lines

► These changes will not take effect until the next IPL, so you must grant this user ID access
to the VSWITCH for this z/VM session. This is done as follows:
==> set vswitch vsw1 grant rh6gold

8.1.3 Preparing RH6GOLD bootstrap files
Now that the RH6GOLD user is defined, you must create the PARM and CONF configuration
files used by the RHEL 6 installer. To save time, you should copy the RH6CLONE PARM-RH6 and
RH6CLONE CONF-RH6 files, then make the necessary changes. Perform the following steps:
► Now in your 3270 session, Logoff of MAINT and logon to LNXMAINT.
► The three files RH6CLONE PARM-RH6, RH6CLONE CONF-RH6, and RHEL6 EXEC should exist on
the LNXMAINT 192 (D) disk as they were copied in 4.7.5, “Copying files associated with this
book to LNXMAINT” on page 60. Copy these files to new files with a file name of RH6GOLD:
==> copy rh6clone * d rh6gold = =
► Change the CMSCONFFILE variable in the PARM-RH6 file to point to the new CONF file:
==> x rh6gold parm-rh6
root=/dev/ram0 ro ip=off ramdisk_size=40000
CMSDASD=191 CMSCONFFILE=RH6GOLD.CONF-RH6
vnc vncpassword=lnx4vm
► Change the DASD, HOSTNAME and IPADDR variables in the RH6GOLD CONF-RH6 configuration
file. For these values, you may want to refer to the worksheet in section 2.7.4, “Linux user
ID worksheet” on page 18. Also, add one line with the METHOD= parameter pointing to the
