+ Integrate the root filesystem generated by Buildroot as an
+ initramfs inside the kernel image. This integration will
+ take place automatically.
+
+ A rootfs.cpio file will be generated in the images/ directory.
+ This is the archive that will be included in the kernel image.
+ The default rootfs compression set in the kernel configuration
+ is used, regardless of how buildroot's cpio archive is configured.
+
+ Note that enabling initramfs together with another filesystem
+ formats doesn't make sense: you would end up having two
+ identical root filesystems, one embedded inside the kernel
+ image, and one separately.
