So far, with both a reasonably modern distribution (Ubuntu 22.04 Jammy)
and a reasonably current kernel (6.1) on arm64, this just works (two
NetBSD sparc64 have ther NFS roots served from this). I don't expect
it to break for the foreseeable future - keep in mind that "we don't
actively support it" does not mean "doesn't work".

The usual candidate for that is nfs-ganesha, except it does NFS v3,
v4.0, v4.1, v4.2 and 9P.

Kind regards,
