Through the zonecfg utility, the file-mac-profile can be set to one of the following values (see note below). All of the profiles except none will cause the /var/pkg directory and its contents to be read-only from inside the zone.

* none

Standard, read-write, non-global zone, with no additional protection beyond the existing zones boundaries. Setting the value to none is equivalent to not setting file-mac-profile property.

* strict

* fixed-configuration

IPS packages, including new packages, cannot be installed.

Persistently enabled SMF services are fixed.

SMF manifests cannot be added from the default locations.

Note:

zonecfg file-mac-profile Property

By default, the zonecfg file-mac-profile property is not set in a non-global zone. A zone is configured to have a writable root dataset.

In a solaris read-only zone, the file-mac-profile property is used to configure a read-only zone root. A read---only root restricts access to the runtime environment from inside the zone.
