I'm copying a big archive of files from a Linux host to an external USB hard drive, that will then plug into a macOS host. The copy should preserve the archive's many symbolic links (ln -s). What filesystem should I format the external disk as?
Not exFAT, because that doesn't support symlinks.
ext4 can be mounted only read-only, via e.g. ext4fuse.
Something else, that can mount read-write? (Must also be writable by the original Linux host, Ubuntu 16.04.)
