Yes I'm sure. It's all host on path type nfs4 and in options also
vers=4.2.

Also the bog standard auto.net these days has code to mount using NFSv4.

That's the weirdness I meant. But it's not true, these days and hasn't
been for years. Or maybe it's hidden? But I can do, for example:

# mount zippy:/tmp /mnt/foo  
# mount|grep zip
zippy:/tmp on /mnt/foo type nfs4 (rw,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=10.0.2.119,local_lock=none,addr=10.0.2.126)

I don't have anything about that in fstab. This is actually a tmpfs
mount where I have fsid=something in /etc/exports but I don't know if
that's required today. zfs mounts the same way from zippy and I don't
have any fsid stuff there. Of course it could be handled automatically.

Autofs mounts a little differently, this is like the old way:

zippy:/ on /net/zippy type nfs4 (rw,nosuid,nodev,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=10.0.2.119,local_lock=none,addr=10.0.2.126)
zippy:/tmp on /net/zippy/tmp type nfs4 (rw,nosuid,nodev,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=10.0.2.119,local_lock=none,addr=10.0.2.126)

Good to know.
