title: controlling the boot screen on Linux embedded app
body: <p>In embedded programming, it's often needed to replace the default Linux boot output by some custom 'loading' animation or splash screen from power-on to up-and-running.</p>
  
  <p>What is the way to achieve this?</p>
  
  <p>Is there a way to use the same 'process' throughout the whole boot sequence for that?</p>
  
  <p>How can this be solved?  I'm guessing we need a home-brew kernel for that?</p>
  
  <p>Thanks!</p>
