The original plan was to build it in the US in the first place. Steve Jobs did not trust that China wouldn't rip off everything about the iphone. He was firmly against the idea of China making the iphone until Apple got him to take a tour a new facility built just for making the new device. China fronted all the funding and manpower to build the facility to make the phone and they did it very, very fast. Steve was instantly smitten.
So it's actually rather ironic that long after his death, there's talk of making it in America.
Here's the thing. Bcachefs is still under development, and Kent is really careful with his filesystem. This happens to me every now and then if I havent rebooted in a long time or theres a kernel update with filesystem changes it doesn't like. The trick is to skip the userspace fsck code and pass the -k flag so it uses the kernel fsck code which is much farther along. I've never lost anything on this filesystem and its messed up in lots of bizzare ways.
