Well yes, but that's what we're talking about transferring over. I don't know if it's simply a matter of recompilation either, as I've heard it mentioned as a reason why the Alien Dalvik on the Jolla phone can't be upgraded to the 4.4 version found on the tablet. Also there's no migration code so they couldn't upgrade existing Alien Dalvik installations, but the kernel version problem would be a showstopper. I have no idea what the dependency entails, but as Google freely patch the Linux kernel as they see fit, I wouldn't be surprised if 4.4 had a minimum kernel version.

So I'm pretty sure I'll wait
