Subject: [PATCH 1/1] docs: nfsroot: Document that nfsvers=2 is the default

Nfsroot uses nfsvers=2 by default (as in fs/nfs/nfsroot.c), unlike is
specified in a modern nfs man page. Document this.

Hi all,

I just figured out that NFS v2 is the default version when mounting root
over NFS. It'd be nice to tell in documentation this is actually the case.

Another option could be to change the default to something sensible. That
would have potential for breaking something though. I wonder what others
think.
