Given how much people love systemd I'm sure it provides an equivalent function under a different name. There might even be some sort of "legacy compatibility" implementation of rc.local. Out of curiosity, is there a specific time when this command would be run? Is it something you can add as the last step init performs before you log in or does it have to happen before something else? That would make a big difference in where/how you add it. -Ben
