That is an interesting point. I already have an old netbook running antiX Linux but I use it for several other projects too. For SkySigner I wanted to create a separate bootable USB OS so I could experiment with a more isolated environment without buying new hardware. I managed to build the system and boot from the USB drive but it currently shuts down shortly after starting. That is the problem I am working on now :D Your approach of keeping the bunker locked until manually unlocked is also something I want to look into.
