If you have an initramfs, then the kernel uncompresses it at boot time,
and executes the /init script/application in this initramfs. And that's
all the kernel does when an initramfs is present: it's the job of the
initramfs initialization procedure to mount the real root filesystem
and switch to it.
So if you have an initramfs, it's normal not to see the typical:
VFS: Mounted root (nfs filesystem) on device 0:14.
message in your boot log.
