122 Preparing the Script Files for Deployment Using Embedded Linux
Utilities Used
grub — Used in conjunction with the kernel image and initial ramdisk files,
along with the unattended answer file to install the operating system.
Variables Used
• DT_OS_DISK — Sets the disk on which to deploy the Red Hat
Enterprise Linux Server operating system.
• DT_OS_SRC — Sets the location from where to copy the kernel image
and
initial ramdisk files.
External Dependencies
The DT_PLATFORM variable is set during deployment by tkenvset.sh using
platform discovery.
The lininst.sh script uses the
unattended answer file in conjunction with the
grub utility and kernel image and initial ramdisk files to install the operating
system files. See "ks.cfg (for Red Hat Enterprise Linux Server Versions 3 and
4) and ks-rhel5.cfg (for Red Hat Enterprise Linux Server Version 5)" for more
information about preparing the
unattended answer file.
ks.cfg (for Red Hat Enterprise Linux Server Versions 3 and 4) and
ks-rhel5.cfg (for Red Hat Enterprise Linux Server Version 5)
Depending on the version of the Red Hat Enterprise Linux Server operating
system, the ks.cfg or ks-rhel5.cfg files are the default names of the answer files
that you use to automate an unattended Red Hat Enterprise Linux Server
installation. A sample copy of the ks.cfg/ ks-rhel5.cfg files are provided as part
of the DTK download in the /opt/dell/toolkit/template/configs directory. The
ks.cfg/ks-rhel5.cfg files contain the headings and parameters that instruct the
installation utility to perform various configuration tasks. Before a full
deployment can be run, you must edit all appropriate headings and
parameters, as necessary.
NOTE: The sample file provided to install Red Hat Enterprise Linux Server (version 5)
is named ks-rhel5.cfg. To use the sample ks-rhel5.cfg file to install Red Hat
Enterprise Linux Server (version 5) using lininst.sh, ensure that you rename the file
to ks.cfg.
NOTE: See your operating system documentation for instructions on modifying the
options in the ks.cfg/ks-rhel5.cfg file to customize the scripted installation of your
operating system.
