Preparing the Script Files for Deployment Using Embedded Linux 125
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 Version 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 Version 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.
When you have completed all necessary modifications of the ks.cfg/ ks-
rhel5.cfg file, save the completed file in the /opt/dell/toolkit/systems/<target
system> directory.
Install Linux Using lininst.sh
On a Linux system, edit the /etc/exports file. If the folder you want to share is
/home
, then /etc/exports file should contain the “ /home *(rw) ” line. Restart the
NFS Service on your system and copy the relevant OS images to the NFS share.
