There is a list of 'stable_properties' that vendor_init can use as property triggers for Treble property compliance. This list came about since init parses init scripts before all partitions are mounted and therefore before all property context files are available, such that init cannot use the normal SELinux mechanisms for determining if a given property is vendor_init readable. Currently though, we require all partitions that would contain property context files to be mounted during first stage mount, so we can use the normal SELinux mechanisms here, so this change deprecates the stable_properties list and moves init to use SELinux to determine if a property can be a trigger. Bug: 71814576 Test: vendor_init fails to use non-readable properties as a trigger Test: vendor_init successfully uses readable properties as a trigger Change-Id: I6a914e8c212a3418cbf4a8a07215056aad2e0162
