➜ ~ zfs sharenfs=on tank
➜  ~ showmount -e
clnt_create: RPC: Program not registered
➜  ~ exportfs
/mnt/zfs        10.0.0.0/8
/tank           <world>
/srv/media      <world>
➜  ~ zfs share -a
➜  ~ showmount -e
clnt_create: RPC: Program not registered


On my client PC, I get this message:
dorito :: ~ » sudo mount -t nfs 10.1.0.100:/srv/media /mnt/fs0


    32 ↵
mount.nfs: requested NFS version or transport protocol is not supported


BTW, I'm using the contrib packages. I'm going to try backports next.
