I don't understand yet, why you want to use Containers, LXC or Dockers at all: You need to have full access to the host and it hardware at low level and don't want to use any isolation or virtualization aspects at all. If you just want to redeploy a complex setup within minutes, you may just need to use a prepared backup of your hosts, or an layered setup with an read-only image and an writeable layer for the changes.<br>
