Subject: [PATCH 0/7 V4]  The NFSv4 only mounting daemon.

nfsv4.exportd is a daemon that will listen for only v4 mount upcalls.
The idea is to allow distros to build a v4 only package
which will have a much smaller footprint than the
entire nfs-utils package.

exportd uses no RPC code, which means none of the 
code or arguments that deal with v3 was ported, 
this again, makes the footprint much smaller. 

The following options were ported:
    * multiple threads
    * state-directory-path option
    * junction support (not tested)

The rest of the mountd options were v3 only options.

V2:
  * Added two systemd services: nfsv4-exportd and nfsv4-server
  * nfsv4-server starts rpc.nfsd -N 3, so nfs.conf mod not needed.

V3: Changed the name from exportd to nfsv4.exportd

V4: Added compile flag that will compile in the NFSv4 only server

Steve Dickson (7):
  exportd: the initial shell of the v4 export support
  exportd: Moved cache upcalls routines into libexport.a
  exportd: multiple threads
  exportd/exportfs: Add the state-directory-path option
  exportd: Enabled junction support
  exportd: systemd unit files
  exportd: Added config variable to compile in the NFSv4 only server.
