extlinux, a simple bootloader for legacy-BIOS environments, like (by default) Qemu.
This uses the same implementation as `boot.loader.generic-extlinux-compatible` to generate the bootloader configuration, but then actually also installs `extlinux` itself, instead of relying on something else (like an externally installed u-boot) to read and execute the configuration.
Any options affecting the config file generation by `boot.loader.generic-extlinux-compatible` apply, but `boot.loader.generic-extlinux-compatible.enable` should not be set to `true`.
Since the bootloader runs before selecting a generation or specialisation to run, all sub-options, similar to e.g. {option}`boot.loader.timeout`, apply globally to the system, from whichever configuration last applied its bootloader (e.g. by newly `nixos-rebuild switch/boot`ing it or by calling its `.../bin/switch-to-configuration switch/boot`)
