APEX configs have supported only 'service' definitions. For those services relying on 'on' trigger actions, we had to have separate config files installed in read-only partitions (e.g. /system/etc/init). This was suboptimal because even though APEXes are updatable, read-only partitions are not. Now, 'on' is supported in APEX configs. Putting 'on' trigger actions near to service definitions makes APEX more self-contained. 'on' trigger actions loaded from APEX configs are not sticky. So, events happens before loading APEX configs can't trigger actions. For example, 'post-fs-data' is where APEX configs are loaded for now, so 'on post-fs-data' in APEX configs can't be triggerd.
