PC-BSD is a new FreeBSD 5.3 distribution, with a graphical installer and KDE 3.4 as its desktop. A new beta version was just released, and though I can't say I have much experience with FreeBSD, or any *BSD for that matter, I was curious enough to try it. And I'm glad I did. From a desktop user's point of view, completely oblivious to the many virtues and sound foundation of all things BSD, all I really ever wanted was an OS that is solid, easy to install and, well ... fun to work with.
seems more and more *nix distros go live-cd these days.
the solution that pc-bsd is using seems similar to what gobolinux is doing (self contained apps and so on) only that gobolinux keeps the libs in seperate dirs.
in fact i have been thinking about giving gobolinux a spin and see how it behaves when used...
