title: Does linux init process run in kernel or user mode?
body: <p>I am trying to learn linux kernel, in TLDP the linux kernel 2.0 book. Is init a process or kernel thread i don't know the exact difference though. And does it run in physicial or virtual memory space? Kernel related stuff usually use physicial memory space but if it is a process thing could change. </p>
  
  <p>Can anyone share their knowledge/experience on that.</p>
