Introduction

The framework is the reference platform described in Brian A. Seklecki's Paper and Presentation on the project.

It is composed of a series of Bourne shell scripts that illustrate a method by which standard BSD system builds can be pruned and optimized for use in Embedded/Appliance platforms such as Compact Flash booting environements.

The system a Profiled BSD Distribution customized to your needs through the scripts in resulting in a commercial network OS-like "firmware" image for your platform.

This adds managability, scalability, simplicity to the process of using BSD as an embedded platform on frequently low-power diskless systems.

Details

Like most documentation, much explanation still lies in the Paper on the project, however some attempts have been made to illustrate.

The system is best illustrated using two diagrams composed during planning:

Scripts

There are four major components / scripts which accomplish descrete functions:

• make_dir_mdrd.sh -- build the root file system in the MD/RD kernel image
• make_dir_cfrd.sh -- build the /usr file system includings ports / pkgsrc
• rd_image.sh -- build an md(4)/rd(4) compatible image and insert it into /{,net}bsd
• cf_image.sh -- build a on-disk image to burn to your CF boot media with identical geometry
