Sorry, somewhere in this thread I had clicked the wrong
reply button.

Talking about initramfs: I am still trying to become
familiar with this stuff. I have found a lot of small
pieces of information (still reading), and the cpio
stuff in the kernel usr directory. But I have 2 questions:

Why is the initramfs built at the beginning of the
kernel build procedure? Wouldn't it be more reasonable
to build it when all kernel modules are available?

And why is it compiled into the kernel at all? The
README in Documentation/early-userspace says

<quote>
"Early userspace" is a set of libraries and programs that provide
various pieces of functionality that are important enough to be
available while a Linux kernel is coming up, but that don't need to be
run inside the kernel itself.
</quote>

So why compile it into the kernel? IMHO it would be more
flexible to load the early-userspace stuff similar to initrd
via the grub command line. Compiling it into the kernel
could be optional.
