- /data/gsi/ota/* now has the type ota_image_data_file. At runtime during an OTA, update_engine uses libsnapshot to talk to gsid to create these images as a backing storage of snapshots. These "COW images" stores the changes update_engine has applied to the partitions. If the update is successful, these changes will be merged to the partitions, and these images will be teared down. If the update fails, these images will be deleted after rolling back to the previous slot. - /metadata/gsi/ota/* now has the type ota_metadata_file. At runtime during an OTA, update_engine and gsid stores update states and information of the created snapshots there. At next boot, init reads these files to re-create the snapshots. Beside these assignments, this CL also allows gsid and update_engine to have the these permissions to do these operations. Bug: 135752105 Test: apply OTA, no failure Change-Id: Ibd53cacb6b4ee569c33cffbc18b1b801b62265de
