If I recall correctly, you can force the behavior where the client sees the exact same type as the server has on the filesystem.

I had not found that documentation.

That document seems a bit out of date when it comes to the latest Fedora.  I'm doing this on F35, but I think F34 is
pretty much the same in this area.

On the server, there is no /etc/sysconfig/nfs file.  If I edit a file with that name and then start the nfs-server the file
then becomes nfs.rpmsave.

In looking at rpc service files I see that rpcbind.service has an EnvironmentFile=/etc/sysconfig/rpcbind.

tried adding such....

[egreshko@f35ser system]$ cat /etc/sysconfig/rpcbind
#
# Optional arguments passed to rpcbind. See rpcbind(8)
RPCBIND_ARGS="-V 4.2"
RPCNFSDARGS="-V 4.2"

But no luck.

Ideas?
