Is anyone feeling less clueless than me? I'm out of ideas now and hoping for

I set up a new NFS server in the last weeks or so and had this weird
problem where I couldn't most an NFSv4 export on clients.
After a lot of head scratching, I discovered two things:
1. On the NFS server, only NFS server 4.0 support was needed
2. On all NFS clients, including the NFS server which mounted other NFS
mounts, all NFS client options had to be selected or the mount would
fail. It didn't matter specifying nfsvers=4.0 as a mount option, it
failed if there was no NFS client kernel support for 4.1/4.2.
I don't know why, I just figured that it was something to do with the
new kernels (running 5.4.x.)
