Introduction

What is tiny-initramfs-core

tiny-initramfs-core is:

A very minimalistic initramfs implementation for booting Linux systems. It is designed for systems where a full initramfs (such as dracut or initramfs-tools) is too large, but where at least some functionality of an initramfs (e.g. mounting the /usr filesystem) is required. Without kernel modules it is less than 16 kiB in size.

tiny-initramfs has less features and is less extensible than full-fledged initramfs implementations, and supports only specific use cases.

This package contains the init binary as well as the mktirfs script that may be used to create working initramfs images, while not replacing the initramfs implementation used on the current system.
