I don't think lack of external adoption is a terribly useful data point either way at the minute. While the feature is controversial a lot of the OSs will probably hold off on it (because it's effort to handle out of tree stuff and folks are really busy) and there's not that many out there which support random externally written packages (which is the major push for exporting the feature to userspace) in the first place. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
