When booting core-image-tiny-initramfs, since we want to live on initrd, on purpose, we never find a rootfs image to switch root to, this causes init to show an error as it would with other images, this patch replaces the message shown to the user, avoiding confusion when it was indeed a successful boot.

# Simple initramfs image artifact generation for tiny images.
|

DESCRIPTION = "Tiny image capable of booting a device. The kernel includes \
|
|
the Minimal RAM-based Initial Root Filesystem (initramfs), which finds the \
|
|
first 'init' program more efficiently. core-image-tiny-initramfs doesn't \
|
|
actually generate an image but rather generates boot and rootfs artifacts \
|
|
into a common location that can subsequently be picked up by external image \
|
|
generation tools such as wic."
