I got a bootable NixOS iso down to 91 MB. Pointed Claude at the Nixpkgs repo and asked it to strip things aggressively and inspect the build closure iteratively.
I miss tomsrtbt and all the other single floppy distros, it was surprisingly complete for 1.44MB (including networking, with more protocols than the average browser, and text editors): https://web.archive.org/web/19990506100919/http://www.toms.n... (mulinux iirc boasted about having 100 commands or something like that)
