There is one initrd use case in my mind, it can be extended to co-work
with overlayfs as a kernel built-in solution for initrd(compressed fs
image)+overlayfs.   Currently we can use compressed fs images
(squashfs or erofs) within initramfs,  and kernel loop mount together
with overlayfs, this works fine but extra pre-mount phase is needed.

Thanks
Dave
