I was happy to see that FreeSBIE 1.1 was released today. FreeSBIE is a live CD version of FreeBSD. Version 1.1 offers FreeBSD 5.3 RELEASE as the underlying OS. If you've used Knoppix to get familiar with Linux in a live CD environment, you should give FreeSBIE a try.
New for this version are the release announcement, a manual, and the list of packages installed on the live CD.
