Hi,
1.I think that vmlinux refers to vmlinzx correctly .In linux booting,PC first
check RAM information,after that,pc start loading OS'information.But,there is a
problem:how to load it?In unix,firstly we must mount filesystem to execute
program.Before loading os'information,we dont have any filesystem.In order to
solve it,We make a boot image,which includes any configure information to
initial/start a operation system.The image as if seem to vmlinxx.Additional we
prepare to save space(RAM?),the image is compressed as one type of file,which
refer to nz.By the way,after compiling kernel,we can find the vmlinzx in /boot
in kernel source.It should be a binary file i rember.
2.In my view,the init is a root process.Aftet loading os susccsful,init start
taking over the systm.For example,a user to login in,init invoke responding
login process;a web request ,which can invoke (stocket'process?).but child
process will fork parent process firstly,include all information
:stack,heap,text,var.These information will change into its value according to
child process once it is to be executed .
Recently i read[linux programming interface].i think it should help you.
Best regrads.

Hi All !
In my learning of linux there is the stupide questions i would like to ask you.
1- Why the name of the kernel is vmlinux ?
What is the origine of this name ?
Perhaps you know why ?
Tell me please or give the link which can explan it.
2 - When linux start the init process launch the default shell process and give
the prompt. The others process as linux commands or users process are the forks
of this first shell process ?
Can you explan simply this point or give me the link which can help me please
in the starting of linux.
Do something as everybody is good but know why, is better to do it.
Help please.
