After installing and customizing an Oracle Solaris 11 non-global (solaris brand) zone, you execute commands: # zonecfg –z myzone ‘set…

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

Permits updates to /var/* directories, with the exception of directories that contain system

configuration components.

IPS packages, including new packages, cannot be installed.

Persistently enabled SMF services are fixed.

SMF manifests cannot be added from the default locations.

Logging and auditing configuration files can be local. syslog and audit configuration are fixed.

* flexible-configuration

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.
