A base layer update can cause local customization of shared files to be lost.

Lotus Notes has a configuration file that is placed under the Program Files directory that is shared across all users. The base layer must initially provision the file for Lotus Notes to function properly. However, the file is then modified locally to maintain the user configuration.

Without a base layer override policy, each base layer update or Enforce All Layers operation causes user customization to be lost.

1

In the Horizon Mirage Management console, expand the Image Composer node and select Layer Rules.

2

Add the configuration file path to the Do Not Override By Layer policy section.

The base layer version of the file is provisioned to users who receive Lotus Notes for the first time, but is not delivered to existing Lotus Notes users.
