To summarize a few notes so far: The docs* suggest that tmpfs can do EA for certain namespaces, so it should not be the (only) reason for this issue * https://docs.kernel.org/filesystems/tmpfs.html The pattern is 100% consistent over numerous uploads that precisely arm64, riscv64, and s390x is able to deal with EA and the other not. It's not an intermittent problem. The following shell command should roughly emulate what netatalk does in C code with system calls: sudo setfattr -n user.org.netatalk.has-Extended-Attributes -v yes /path/to/existing/dir/or/file This requires the "attr" package to be installed. Please let me know if you want me back on IRC for a follow-up session later. :) Best, Daniel
