Hi Team, Android and android recovery based implementation for Linux, generates ota package which is a zipped archive. I observed that xattr gets dropped when creating zip archive and therefore after OTA system will not boot if IMA_APPRAISE_SIGNED_INIT is used. This essentially means that IMA may not be used in commercial products requiring OTA or I missed something or there is a workaround to such problem. https://source.android.com/devices/tech/ota/tools Regards, Rishi
