OneFileLinux: A 20MB Alpine metadistro that fits into the ESP
One File Linux is a compact live distribution for UEFI computers, fitting in a 20MB file. It operates without installation, ideal for systems without USB drives, using the EFI partition for booting. It supports disk encryption and can leverage internal hardware like WiFi cards. Instructions cover Mac, PC, and USB use, with customization options available.

One File Linux is a unique live Linux distribution contained in a single ~20MB file that can run on any UEFI computer without the need for installation. Users can simply copy the file to the EFI system partition and boot from it. The main advantages include not requiring additional partitions, USB flash drives, or boot managers like GRUB. It can work with disk encryption and is particularly useful for scenarios where USB flash drives are not an option. The creator's personal goal was to utilize a laptop's internal PCIe WiFi card for specific tasks. Instructions are provided for running One File Linux on both Mac and PC systems, as well as from a USB flash drive. Users can also customize and build their own version based on Alpine Linux and the vanilla kernel.

Booting Linux Off of Google Drive
A programmer's competitiveness leads to booting Linux from Google Drive, facing challenges like networking setup and mounting an Arch Linux root from an S3 bucket. Despite setbacks, Linux boots successfully, integrating Google Drive but facing performance issues and complexities.
Booting Linux Off of Google Drive
The author successfully booted Linux from a Google Drive root independently, using FUSE programs and custom initramfs on Arch Linux. Challenges with networking, permissions, and dependencies were addressed through manual solutions.
Fiwix: Unix-like kernel for the i386 architecture
The Fiwix operating system kernel, a UNIX-based system, emphasizes POSIX compatibility. It offers preemptive multitasking, POSIX compliance, virtual memory management, and supports various filesystems and hardware platforms. Fiwix serves as an educational tool with simple kernel code for students and enthusiasts. Installation is feasible from CD-ROM or floppy disk with minimal hardware requirements. Users are cautioned about potential bugs and incomplete features due to its early development stage. More details are available on the Fiwix GitHub Repository or website.
No more boot loader: Please use the kernel instead
A new approach called nmbl aims to replace GRUB with a Linux-based solution using the kernel itself. Red Hat's proposal consolidates components into a unified kernel image for a streamlined boot process.

This is crying out for an update, IMHO.
This is the last I've heard of such an effort: https://www.cnx-software.com/2019/12/03/western-digital-risc...
It worked by building the system into the initramfs, then using a kernel feature to basically bake the initramfs into the kernel image, and then using efistub to make the kernel bootable
Shame it's not been updated in so long.
"20 MB Linux.EFI" ...
