// multiple times, sometimes prior to the real /data being mounted. That causes
// keystore2 to try to open a file in /data, causing it to panic or have to be
// killed by vold later, causing problems (vold failing to connect to keystore2,
// or keystore2 operations erroring out later). As a workaround to keep FDE
// working, ignore these too-early calls to earlyBootEnded.
