From 341644d657d84de0b7a2299d311503ea71418af3 Mon Sep 17 00:00:00 2001 From: Bill Peckham Date: Tue, 17 Sep 2019 17:11:50 -0700 Subject: Moving recovery resources from /system to /vendor This change is part of a topic that moves the recovery resources from the system partition to the vendor partition, if it exists, or the vendor directory on the system partition otherwise. The recovery resources are moving from the system image to the vendor partition so that a single system image may be used with either an A/B or a non-A/B vendor image. The topic removes a delta in the system image that prevented such reuse in the past. The recovery resources that are moving are involved with updating the recovery partition after an update. In a non-A/B configuration, the system boots from the recovery partition, updates the other partitions (system, vendor, etc.) Then, the next time the system boots normally, a script updates the recovery partition (if necessary). This script, the executables it invokes, and the data files that it uses were previously on the system partition. The resources that are moving include the following. * install-recovery.sh * applypatch * recovery-resource.dat (if present) * recovery-from-boot.p (if present) This makes the applypatch executable a vendor module. This change supports making dependencies of the applypatch executable available to applypatch, which is now on vendor. Since install-recovery.sh is now a vendor service, we add the applypatch/vendor_flash_recovery.rc file to /vendor/etc/init to start the service. Bug: 68319577 Test: Ensure that recovery partition is updated correctly.
