FreeSBIE is a LiveCD based on the FreeBSD Operating system, or even easier, a FreeBSD-based operating system that works directly from a CD, without touching your hard drive. We also develop a simple to use and easily extendable toolkit used for the creation of the CD. This toolkit can also be used to make embedded images a-la miniBSD or nanoBSD.
