> Typically, an initramfs is not needed, but may be necessary for:

Mounting an encrypted, logical, or otherwise special root partition Providing a minimalistic rescue shell (if something goes wrong) Customize the boot process (e.g., print a welcome message) Load modules necessary to boot (e.g., third party storage drivers) Anything the kernel can't do that's usually handled in user space

So a lot of things which are not emacs.
