It's poorly supported today. Nobody has tested the concurrency kit changes on it. And ck is now mandatory. We don't even know if it works or not. Last time we asked, it took quite a while to find users. It maxes out at 256MB of RAM. This is barely large enough for FreeBSD to run in. The hardware was last made almost a decade ago. It uses non-standard non-mainstream boot loaders (boot technology has moved on from redboot). The cost of doing API sweeps, make universe runs, etc exceeds the benefit to the project. So, given all these factors, it sounds like a good candidate for retirement. Therefore, I'd like to remove it on July 15th. Comments? (please keep them on topic to this specific thing: there's other things that may also be past their freshness date, we'll discuss those in a separate thread). Warner
