 +
 +==== A note on dependencies and Apps Audit ====
 +
 +When an extension is placed in the OnBoot or OnDemand list using Apps Audit the extension and all it's dependencies are removed from the list of extensions available to be added (the left hand window in Apps Audit). This can result in some extensions apparently disappearing. An example is alsa and alsamixergui:
 +
 +If a user wishes the alsa sound system to be loaded at boot time the alsa extension is placed in OnBoot, and as alsa-modules is a dependency it will also be removed from the list of extensions available for selection in the left-hand window. The user may occasionally require use of alsamixergui and so places that in OnDemand.
 +
 +If later alsa is removed from OnBoot, either accidentally or because the user wishes to prevent alsa loading at boot time it does not reappear in the list of extensions available for selection. As a consequence it cannot be added back to OnBoot using Apps Audit. The reason for this is that alsamixergui is in the OnDemand list and has alsa (& consequently alsa-modules) as a dependency so alsa (& alsa-modules) do not appear in the list of extensions available to be added to OnBoot or OnDemand. To be able to restore alsa to OnBoot either the file OnBoot.lst in the tce directory must be edited manually or alsamixergui must be removed from OnDemand, then alsa will be added back to the list of available extensions and can be selected for OnBoot. If the latter method is used alsamixergui will need to be replaced in OnDemand after alsa has been added to OnBoot.
 +
 +This is only one example, but illustrates a possible cause if an extension is not listed as available by Apps Audit, but has been downloaded to local storage.
