By popular demand, the source tree for the Lumina project has just been moved to its own repository within the main PC-BSD project tree on GitHub.
In addition to this, an official FreeBSD port for Lumina was just committed to the FreeBSD ports tree which uses the new repo.
By the way, here is a quick usage summary for those that are interested in how “light” Lumina 0.6.2 is on PC-BSD 10.0.3:
System: Netbook with a single 1.6GHz atom processor and 2GB of memory (Fresh installation of PC-BSD 10.0.3 with Lumina 0.6.2)
Usage: ~0.2–0.4% CPU and ~120MB active memory use (no apps running except an xterm with “top” after a couple minutes for the PC-BSD tray applications to start up and settle down)
