From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Fri, 4 Mar 2022 00:07:29 +0000 Subject: [PATCH] UserDataPreparer: reboot to recovery for system user only With the next CL, old devices might contain a combination of old users with prepareUserStorage error checking disabled and new users with prepareUserStorage error checking enabled. Factory resetting the whole device when any user fails to prepare may be too aggressive. Also, UserDataPreparer already destroys the affected user's storage when it fails to prepare, which seems to be fairly effective at breaking things for that user (absent proper error handling by upper layers). Therefore, let's only factory reset the device if the failing user is the system user.
