When calling the completion code, kitty tries to access the config directory and create it if it does not exist. If kitty has no permission to create it, a temporary directory will be created instead. This will fail on a read-only file system because that raises an `OSError` and not a `PermissionError`. In practice this happens when building kitty on macOS Catalina using Nix because `HOME` is set to `/homeless-shelter` for purity and `/` is a read-only filesystem.
