Boot fast, argue faster
Boot Naked Linux
A coder made Linux boot almost instantly and the comments instantly started fighting
TLDR: A developer built a super-minimal version of Linux that starts almost instantly by running just one tiny program instead of a full operating system. Commenters were split between calling it a fun experiment, suggesting practical uses, and bluntly asking why anyone would want this at all.
A programmer decided modern computers have gotten way too pampered and asked a delightfully chaotic question: what if Linux started up with almost nothing at all, just enough to run one single program and then shut down? The result was a tiny stripped-down setup that can launch in under a second inside a virtual machine. In plain English, this is like turning a giant office building into a one-room kiosk just to prove it can open faster than the mall.
But the real fireworks were in the comments, where the crowd split into classic internet factions: the tinkerers, the skeptics, and the nostalgics. One camp loved it as a pure experiment, tossing in extra nerd candy like BusyBox and other tools for making a mini system even more usable. Another camp came in with the brutal reality check: what is the point? One commenter basically said, if you only want one tiny task, old-school DOS might be even faster, and also your actual computer still takes much longer to wake up than the software does.
Then came the dreamers, who immediately turned this into a fantasy product pitch: a dual-boot machine that opens straight into Neovim for instant writing with no distractions. And, because this is the internet, someone had to note that a Rust version already did something similar, while another reminded everyone that Linux From Scratch has been flexing for 27 years. So yes, the project is tiny—but the comment drama around it is gloriously full-sized.
Key Points
- •The article demonstrates a minimal Linux boot setup that runs a single custom init process instead of a full userspace.
- •It provides a small statically linked C program as `/init` that prints a message and powers off the machine using `reboot(RB_POWER_OFF)`.
- •The article explains that modern Linux booting typically involves a boot loader, initrd, initramfs, and fallback logic using `root=`, `rdinit=`, and `init=` parameters.
- •It contrasts the custom one-file initrd with a typical distribution initrd, citing a 73 MB image containing 2,163 files on the author’s PC.
- •It shows how to build the minimal initrd using `gcc`, `cpio`, and `gzip`, and notes common early-boot errors related to archive format, compression, file placement, or architecture mismatch.
