Subject: question : is the init process of kernel running in kernel space or user space?
Date: Mon, 18 Apr 2005 09:36:38 +0800	[thread overview]
Message-ID: <42630F26.3060503@haha.com> (raw)

Hi all,

In the linux system , kernel is often starting up like this :

bootloader -> start_32() -> start_kernel() -> init()

i would like to ask what is the piority level in this starting procedure 
? 0 or 3 ? that means, this start up process are running in kernel space 
or user space ?  or the level is keep changing ?
If it is in kernel space from the very beginning , at which point the 
system is switched into user space ? is it at the time when kernel open 
the shell ?

I am new to linux, hope someone can help me here.


Regards,
TOM
