It would not be type units that would determine when boot is considered 
completed since you cannot reliably rely on that.

AFAIK the android boot process fires an standard broadcasting action 
"ACTION_BOOT_COMPLETED" once system services are up and running in 
memory, which is the time when it considered the boot being completed 
and "stable".
