The kind of tool that I'm waiting for would allow me to log into a machine remotely, then reboot it once into a provided image (which could then run Linux in a ramdisk). I.e., take over the entire machine until it is restarted again. Does something like this exist? I want something like "kexec" but taking over the entire hardware at the lowest possible level. Edit, found this: https://github.com/marcan/takeover.sh https://github.com/marcan/takeover.sh But it's not as low level as I hoped, though it keeps the network running which is nice :)
