System requirements specify the conditions that must be satisfied on the managed device for the policy to be effective. System requirements are specified for each policy to ensure that the conditions necessary for a proper enforcement of a policy are met.
The appropriate default system requirements are included in a policy when it is created. When you create or edit a policy, you can modify or remove the requirements. No default system requirement is available for the Text File and Remote Execute policies.
You can change the system requirement setting if the settings included in the policy are available on different versions or platforms. If not, all the settings configured in the policy are not effective. For example, if the Distribution >= Novell Linux Desktop 9 requirement is removed from the Firefox policy and the policy is specified to be enforced on all platforms, the settings are not effective because the lockdown option for Firefox is available only for the Novell Linux Desktop.
You should remove the system requirement only if you are sure that it will not cause problems. For example, in a Generic GNOME policy created by importing settings from a device, the system requirement is set to the operating system of the device from which the settings were imported. If you have included settings in the policy that are available on other platforms, you can remove or change the system requirement.
IMPORTANT:Even if the requirements are removed and the application version or operating system is incompatible, the policy is enforced but a warning message is generated. If the appropriate application (Epiphany, Evolution, or Firefox) is not installed, the policy is not enforced and an error message is generated.
