Etymology: "Rebooter" is a plain formation: the verb "reboot" with the agent suffix "-er," meaning one who or that which does the action. The noun "reboot" comes first. It is the older word, from "re-" meaning again and "boot," short for "bootstrap," a term for starting a computer from its basic startup code. The "bootstrap" image, of pulling oneself up by one's own boot straps, gave computing its name for a self-starting process, and "reboot" carried the idea of starting that process over again. Adding "-er" produces a word for whatever restarts a machine, whether a person, a switch, or a program. Like many agent nouns formed this way, it follows the pattern of "a thing that does X," so a rebooter is simply something that reboots.
