Not so precise. Those who use old kernels (including me) are not normally lacking of courage, but are short of money, on the order of 10^9 or 10^10 USD. Because most end-users cannot control their upstream, they may face problems such as, but not limited to: 1) Dependency. There are lots of out-of-tree drivers such as NVIDIA, etc. that don't follow kernel development closely. It may be difficult for end-users to modify every of these drivers by themselves. 2) Instability. e.g. Kernels 3.8 and 3.9 have problems with USB WiFi. After the first run of wpa_supplicant any USB WiFi will get defunct until next boot. So I am still using 3.7.10 on an i.MX23. > they need some compatibility which was dropped in newer kernels.

I am not saying that Okajima-san should maintain aufs for old kernels. I just say if he does, it is a reasonable choice.
