Choosing an Embedded Linux-Based Deployment Method 87
Using DTK Utilities and Scripts From a Customized Bootable CD
After the customized bootable embedded Linux CD is created,
IT administrators can take advantage of the sample scripts to automate the
entire deployment process. In this purely CD-based deployment, it is
necessary to add the operating system installation files on the CD media.
Deployment Matrix (Embedded Linux)
Depending on the scope, current business needs, network setup, and process,
you might select any of the suggested methods of deployment. Table 6-1
outlines four typical methods of deployment and the environment most
suitable for each.

(bootable CD)
Relatively
simple
• Necessary if a
network
connection is not
available or is too
slow.
• Can perform a
minimal
installation of
supported Linux
operating systems.
• Any change requires the
creation of a new
bootable CD.
• Limited space on CD for
some operating system
installation files.
• Deployment tasks must
be performed at the
individual target system.
• CDs are read-only media
and require the creation
of a RAMDISK for
temporary data storage.
• Installation time is high.
