84 Choosing an Embedded Linux-Based Deployment Method
Media-Based Local Deployment for Embedded Linux
The general media-based deployment process includes the following steps:
1
Copy the DTK ISO image into a share.
2 Modify the appropriate section in the isolinux / isolinux.cfg file.
3 Reburn the contents into a CD/DVD (master CD/DVD).
4 Boot the target server from the master CD/DVD.
The DTK startup phase mounts the CD/DVD.
The DTK startup phase runs the script (name specified in the
isolinux.cfg
file) from the CD/DVD.
This deployment method is the easiest to assemble, but is the least flexible.
Any change to the system configuration, for example, requires the creation of
a new bootable CD/DVD. This method does not provide a writable media
making it necessary to use predefined and tested configuration files.
Creating a Bootable media
Bootable media can be created using any commonly available CD/DVD
burning software in a two-part process that requires a self-bootable ISO image
with drivers that load from system files. When you create a bootable media,
this image is supplied to the CD/DVD burning software along with the
complete deployment directory structure, which includes all necessary
supporting files to perform the deployment. The CD/DVD burning software
creates an image of the self-bootable ISO image and the deployment files on
the CD/DVD.
NOTE: For more information about creating an embedded Linux-bootable CD/DVD,
see "Running Deployment Scripts and RPMs Using DTK and Embedded Linux" on
