A category into which neither HFS+ nor APFS falls; they both support both hard links and symlinks.  (I think HFS+'s implementation of hard links is *internally* a bit unusual, but they have the full semantics of POSIX hard links.)

The same applies, as far as I know, to all the main Linux local file systems.

So I don't know why Ubuntu (and possibly Debian) use symlinks, or why macOS is using copies, unless they're both trying to support VFAT or something such as that.
