So I guess that means we're back to supporting only the latest two LTS kernel series, those being 4.1 and 4.4 at this time. I had hoped that btrfs was stabilizing enough, and 3.18 was trouble-free enough btrfs- wise, that we could expand that to three LTS series now, as the indications were we might when 4.4 was still new. But it seems that while we did support it a bit longer, say 2.5 LTS series, that couldn't continue until the /next/ LTS came out. Oh, well, it /was/ a bit of a stretch... -- Duncan - List replies preferred. No HTML msgs. "Every nonfree program has a lord, a master -- and if you use the program, he is your master."
