Talos Linux introduced overlays in version 1.7 to allow more flexible customizations of the installer, addressing limitations in earlier versions. Overlays are used to customize the installer before the kernel boots, which is crucial for devices like Raspberry Pi that lack BIOS or UEFI. Extensions, on the other hand, are used to modify the root file system after installation. This feature enables easier and more maintainable custom installations for various hardware, including single-board computers.
