Toot

Idea for a server distro:

• Immutable, consists of a single kernel image (probably a UKI), a single filesystem image, and a single directory for mutable state.
• Directly UEFI-bootable, does not require a bootloader.
• All applications are embedded into the filesystem image, allowing for library and configuration sharing between individual apps so you can tightly integrate various components without duplication.
• The base OS acts as a hypervisor only, running one VM for each service the server provides.
• For each service, the OS re-executes itself in a virtual machine, passing an argument through the command line instructing which of the embedded applications the virtual machine should run and where it should save state files at.
• Updates are run by rebuilding the system image and copying it onto the server, overwriting the old filesystem and kernel images. After replacing the images and rebooting the server, you can then do any needed migration operations.
• OS is distributed in source-code form only, is based upon Linux From Scratch, and can be built entirely from source into a ready-to-use server image on an Ubuntu machine, a Debian machine, or using the server OS itself.
• Docker never comes into the picture.

Horrible idea or does this actually sound remotely useful?
