+ # When mmd package is not included in the image, we need to initialize
+ # `mmd.enabled_aconfig` sysprop instead of `mmd --set-property`.
+ #
+ # This is because of the consideration for devices in Trunkfood and Nextfood
+ # under mmd being launched via AConfig flag. The devices set up zram with
+ # mmd if `mmd_enabled` AConfig flag is enabled, otherwise set up zram with
+ # swapon_all init command. Since AConfig does not support any init script
+ # integration, we use `mmd.enabled_aconfig` copied by `mmd --set-property`
+ # instead of AConfig flag itself and we need mmd.enabled_aconfig to be empty
+ # by default, to let swapon_all command wait until aconfig flag value is
+ # loaded to the system property.
+ # Devices in Trunkfood and Nextfood needs to execute swapon_all command on
+ # `on property:mmd.enabled_aconfig=*` trigger. So initializing
+ # `mmd.enabled_aconfig` sysprop is required on images without mmd package.
+ #
+ # Note that this init file must not be in the image if mmd is built into the
+ # image.
