nfsd, while the PXE terminal client is still able to boot and mount root from 
NFS (provided nfscl_enable="YES" is specified in the /boot/loader.conf of 
PXE's root). so NFS_ROOT does not necessarily require NFSCLIENT, but NFSCLIENT 
certainly seems to require NFSSERVER.

Yes, you should be using NFSCL and NFSD instead of NFSCLIENT and NFSSERVER 
now.  9 includes a new NFS client and server implementation that include NFSv4 
support (and have cleaner code).  GENERIC changed between 8 and 9 to switch to 
the new client and server, but it seems you are using an unmodified kernel 
config from 8 on 9?
