Hi Robert,

Yes I believe the documentation is still accurate. An initramfs image
can either be linked into the kernel image, or passed to the kernel by
the bootloader (e.g. U-Boot)

I use Buildroot to build a kernel with an embedded rootfs that has all
the tools I need for testing an embedded system. I've also used
Buildroot to make a cpio archive of the root filesystem and used that as
an external initramfs.
