An interesting quirk of the ISO 9660 standard is that the first sector of the disc is explicitly undefined, in order to accommodate a platform-specific boot sector. I sometimes wonder how many platforms could be accommodated by a single "polyglot" disc image.

  > The Makefile will download cosmocc automatically. What can go wrong ? > It's recommended that you install a systemwide APE Loader. This command requires sudo access to copy the ape command to a system folder and register with binfmt_misc on Linux, for even more performance. A security nightmare.

    How is this different from all the other installation instructions asking to `curl https://foo/install.sh https://foo/install.sh | sh` or even add a custom apt/rpm repo or just install a deb or rpm locally? They all might get sudo access. I do agree, but the same holds for the above methods too.
