Belenix
I've long wanted to give OpenSolaris a try, but the vmware images I could find didn't boot into X11 and it was generally speaking a hard slog to find anything that ran KDE. I've got an ulterior motive, of course: we sometimes get bug reports about Krita not compiling on Solaris (notably 106891 125439 and 125446, and I want to be able to test fixes. Besides, SunOS was the first Unix I worked on, and I am as sentimental as the next person.
So I was rather delighted at Aaron telling the world about Belenix. This OS must have the coolest logo ever, not to mention the cool Asterix connotations:
The Live CD booted on my laptop without any trouble, but, unfortunately, my wireless network card didn't work. This is the same card that Kubuntu uses successfully during the installation stage to hijack my neighbors w-lan.
Still, that's a minor thing: I'm not one of those who whine "just add this one little feature for me, and I'll use your stuff!" -- I'm sure I could discover how to make it work, or, alternatively, make do with a wire.
More interesting, perhaps is this: KDE really needs to have a unified system administration front end that works on all operation systems. My goodness - OpenSolaris is different -- I had no idea I had become so much indoctrinated with the Linux (Slackware, SuSE and Kubuntu) way of doing things. I couldn't find my way at all...
Another observation: the Belenix guys are cool. They show the readme notes in a real xterm inside vim. How's that for not pandering to the masses! For the rest, there are, as Aaron said, some wierdnesses on their desktop, primarily caused, I think, by having xfce as a basic with KDE overlaid on it. Still, it's cool. Much cooler than Nexenta. If only because of the logo!
Oh, and although I couldn't find, the release notes say Belenix includes KOffice! I guess my Solaris compile problems were already solved, then.
