6. Controlling SysCon Behavior Using Policies
The behavior of the SysCon feature can be customized by using the SysCon policy settings file, which
details the policies in effect for a single system and resides in the top-level settings folder for that system.
For example, the file
sysconenv/data/config/thisSystem/policysettings.xml
contains the
policy settings for the current system. If this file does not exist, the file
sysconenv/data/common/policies/policydefaults.xml
is copied to
sysconenv/data/config/thisSystem/policysettings.xml
and used as the policy settings for
the system.
In order to change SysCon feature policies, the user must edit the policy settings file. The policy settings
file may be edited using an OS-based or EFI shell-based text editing tool.
The following SysCon policies are user-definable. The exact syntax of the policy settings file is
documented in
Appendix B . Note that the OS-based SysCon service also provides policy-driven
behavior that can be customized by the user. These policies and their format are described in detail in
the SysCon Service User’s Guide.
"AlwaysArchiveSystemSettingsCopy"
When this policy is selected, the SysCon feature will copy the extracted settings to a file in the “archived”
folder each time the system is booted. If archival limited by policy or physical space on the SysCon
device, the SysCon feature will remove the oldest copy of the extracted sectings and retain the latest
copy.
"AlwaysRestoreSavedSettings"
When this policy is selected, the SysCon feature will always restore the system to settings from the
“saved” folder when it detects that the current settings have changed. This policy also applies to the
transfer case, in which a replacement system is detected. In this case, settings from the previous system
will be applied to the replacement system.
"AllowSysConKeyUse"
When this policy is selected, the SysCon feature will attempt to detect and use any SysCon Keys that are
inserted into the system. This policy is not selected by default and is not implemented in the initial
release.
"CopySavedSettingsToKey"
When this policy is selected, the SysCon feature will copy the current settings to a SysCon Key (when
present).
