1. How to use initramfs for root filesystem?

Dear all,

I'm trying to understand how initramfs, especially 'init' program is
used as a root filesystem.
Usually I've used 'root=/dev/mtdblock0 rootfstype=jffs2' in kernel
command line for root filesystem and my 'init' program
is laid in mtdblock0 so kernel can find where the 'init' program

But I read initramfs does not required 'root=' command line.
So, if I don't type 'root=' in kernel command line, how the kernel
finds out where the 'init' program exists?
and what kind of filesystem is using for the block that 'init' program

Simply asking,
Can I use kernel command line without 'root=' option? If I can, how
can I use?
