Of course, an initrd on floppy is kind of silly, because you still need to find someplace else to fit the actual kernel - which hasn't fit on a floppy for quite some time.
Do we must need initrd.img to boot system ?
Does this /boot/initrd.img file come out when building kernel ? how to build it?
Your system should have either 'mkinitrd' or 'dracut' to build the initrd image. Some older systems will have 'mkinitramfs'.
I know how to make a initrd image file , but put what data into it? Thanks!
