Explanation/Reference:
How to Loopback Mount a File That Is Usually Not Visible in a Labeled Zone This procedure enables a user in a specified labeled zone to view files that are not exported from the global zone by default.
1. Halt the zone whose configuration you want to change.
# zoneadm -z zone-name halt
2. Loopback mount a file or directory.
For example, enable ordinary users to view a file in the /etc directory.
# zonecfg -z zone-name
add filesystem
set special=/etc/filename
set directory=/etc/filename
set type=lofs
add options [ro,nodevices,nosetuid]
end
exit
Note - Certain files are not used by the system, so that loopback mounting them has no effect. For example, the /etc/dfs/dfstab file in a labeled zone is not checked by Trusted Extensions software. For more information, see Sharing Files From a Labeled Zone.
1. Start the zone.
# zoneadm -z zone-name boot
Note:
* In this Solaris release, you create a ZFS file system share and publish the share as follows:
Create the file system share and define the NFS or SMB share properties by using the zfs share command.
* ZFS File Sharing Within a Non-Global Zone
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.
* If a ZFS file system is mounted and available in a non-global zone, it can be shared in that zone.
* A file system can be shared in the global zone if it is not mounted in a non-global zone or is not shared to a non-global zone.
* If a ZFS file system's mountpoint property set to legacy, the file system can be shared by using the legacy share command.
