(I've > mentioned org-mobile-push, and emacs' own file backup code This is a more serious matter, but it's a judgment call as to whether it stopped working or started working. Some users want permissions to be saved, as well as contents. Others don't. Emacs should support both usages. I'm still puzzled as to why you're observing the problem and I am not. Can you do an 'strace' on an Emacs that's exhibiting the problem? It'd be helpful to see exactly which system calls are being invoked, and the errno value for the failing one. Possibly there is a small workaround here that wouldn't require redesining copy-file.
