I'm aware of the following references: http://www.mavetju.org/mail/view_message.php?list=3Dfreebsd-hackers&id=3D37= 5676 http://www.mavetju.org/mail/view_thread.php?list=3Dfreebsd-stable&id=3D1335= 519&thread=3Dyes >1. Installing a stable FreeBSD build >2. Check out a version of the Build suitable for the project Any changes will need to apply to FreeBSD -current, though they may be back-ported once tested. This means that you will need a -current system at some point. 8-current is reasonably stable at this point and would be my suggestion. >3.

It references various system header files in order to understand the UFS on-disk format. >Lastly- does this project require the know-how's of device drivers? If so,= I >would have to work harder.
