sharenfs is old Solaris syntax for an nfsd implementation that I think
was entirely in the kernel.  I'm not sure if regular FreeBSD implements
that option either.

On Debian GNU/kFreeBSD you'll want to install the freebsd-nfs-server
package.  It's configured in /etc/exports with syntax that differs only
slightly from Linux, e.g.:

> /srv/nfs/example	-maproot=nobody	192.168.1.2

to export that directory (or a mountpoint for a ZFS sub-filesystem),
writable, to that one host.  The mountd service must be restarted to
apply changes in that file.

With a wheezy server I have at least nfsv3 working.  lockd is running
but I'm not sure if it's doing anything.

For some reason I forced nfsd to listen on TCP only, but I'm not sure if
that's essential:

/etc/default/nfsd:
> DAEMON_ARGS="-t"

I also mount the nfs share with options vers=3,proto=tcp but I'm not
sure if I still need to specify that.  Also rsize=32768,wsize=32768
because IIRC the defaults were very low and 32768 is the maximum value.
 And I used the sync option, which may be even faster than async, since
I have a ZIL device on SSD.  But I recommend to experiment, benchmark,
and let us know how it all goes.
