No, the barebox support is for NFSv3 over UDP. This does not prevent you
from using NFSv4/TCP during kernel boot up for the rootfs however.

We would like to support NFSv4 eventually, but given that the we had
to fix a fair share of security issues with the current network stack
and NFSv3 implementation, we should to try to avoid repeating this
in future.

Incidentally, I just created a PR for rust support in barebox:
https://github.com/barebox/barebox/pull/96

The goal is to add smoltcp as TCP/IP stack on top of it.

Then we can look towards supporting TCP protocols like HTTP and NFSv4,
but it will take a while.

This may be the third time that someone asked for NFSv4 support on the
mailing list and it would be useful to know how are you going to use it
and where NFSv3/UDP falls short. Is this because you are using Linux
kernel-nfs-server and NFSv3/UDP is not enabled by your distro or is it
because of something else?

Cheers,
Ahmad
