@abenson I don't think many people read or know about the `README.voidlinux` specific documentation. Having a safeguard, although a not "100%" one, could be useful. What do you think?

A proper safeguard would require adding the same check, but reverse, to `power-profiles-daemon` runit service. Doing that is intrusive, so I didn't do it. There might also be some other edge cases that I haven't thought of. Also this advanced usage of runit isn't really supported by runit well, it doesn't really have a built in way to have dependencies in services or have mutually exclusive services (which is required here) except `sv` shenanigans.
