Hi:
thanks for your kind reply.
my questions are:
1. from the log file, it seems somewhere in kernel, we go through
kobjects one by one.
(it is only my assumption)
And it will do so if I call some functions in fs, like
(sys_open((const char __user *) "/dev/console", O_RDWR, 0) < 0).
If my assumptions above are correct, would you please tell me where
entry point which check each kobject and what it is used for?
2. My kernel seems ready so far because it can successfully keep
running before run_init_process("/sbin/init"), then it tells me "No
init found. Try passing init= option to kernel."
I know the problem comes from I didn't tell the kernel where the
root file system is.
I have googled the "root file system", but they only tell me the
purpose of it and minimum elements it should have.
But I cannot find any information tell me how to let the kernel
know where it is.
I have made a root file system with busybox in it and I also make
it as ext2 format.
where I should and what I have to pass this information to kernel?
BTW, does root file system have any relationship with initramfs and initrd?
appreciate your kind help,
miloody
