>Description:
Sharing a ZFS filesystem over NFS to hosts with a hyphen (-) in their hostnames using 'zfs set sharenfs' does not work.
'zfs get sharenfs'  does return the correct string as set before, but in /etc/zfs/exports the hyphen in the hostname was replaced with a blank.
>How-To-Repeat:
# zfs set sharenfs="-maproot=root foo-bar" systempool/export/test
# zfs get sharenfs systempool/export/test
NAME                                 PROPERTY  VALUE                    SOURCE
systempool/export/test     sharenfs  -maproot=root foo-bar  local
# cat /etc/zfs/exports
[...]
/export/test       -maproot=root foo bar
