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.
