In previous Solaris releases, you could not create and publish NFS or SMB shares in a Oracle Solaris non-global zone. In this Solaris release, you can create and publish NFS shares by using the zfs set share command and the legacy share command with a non-global zone.
とあり，non-global zone では NFS のみ可．
non-global zone で cifs を使いたければ，
samba を利用．
