export a zfs snapshot over nfs

[mike tancsa]

On a backup server, I want to export a zfs snapshot via nfs, but I cant
seem to do it.

given the snapshot is
backup2/zrepl/sink2/nfserver1/images/vms at zrepl_20190902_122114_000

I can do something locally like

mkdir /tmpmount

add

/tmpmount       -maproot=nobody   192.168.13.36

and from the client machine mount /tmpmount.

But if I do on the server

mount -t zfs
backup2/zrepl/sink2/nfserver1/images/vms at zrepl_20190902_122114_000 /tmpmount

and then try and mount from the client, I get a permission denied.

I can work around it by creating a quick clone of the snapshot and
mounting the clone.  But was curious as to why I cant do it the first way ?

server is releng12 and nfsv3
