ZFS sharenfs broken

Hey all,

I'm exposing some ZFS datasets using the `zfs set sharenfs` option.
However, this causes mountd to complain:

==== BEGIN mountd LOG ====
Oct 24 20:19:59 hbsd-os-build-01 mountd[89840]: bad exports list line '/data/build/pub/current	-ro'
Oct 24 20:20:07 hbsd-os-build-01 mountd[14071]: = after op: ro

Oct 24 20:20:07 hbsd-os-build-01 mountd[14071]: = after op: ro
==== END mountd LOG ====

The command I ran for those datasets:

zfs set sharenfs='ro=172.16.1.0/24,-alldirs' rpool/data/build/pub

(Replace that last argument with the other datasets. The same exact
command was used, just with the dataset changed.)

The /etc/zfs/exports file contains:

==== BEGIN exports ====
# !!! DO NOT EDIT THIS FILE MANUALLY !!!

/data/build/pub	-ro=172.16.1.0/24 -alldirs 
/data/build/pub/13-stable	-ro=172.16.1.0/24 -alldirs 
/data/build/pub/cross-dso-cfi	-ro=172.16.1.0/24 -alldirs 
/data/build/pub/current	-ro=172.16.1.0/24 -alldirs
==== END exports ===

I'm a bit unsure of what to do here. I'm not sure if the issue lies in
ZFS or mountd or something else entirely.

`uname -a` shows:
