I can't tell if I'm misremembering or this option used to be in the UI and was removed.
I would swear that there was a dropdown box in the UI to set the timecounter.hardware and I changed it to ACPI-fast on a previous install.
Is this still a thing and I'm just looking in the wrong screens, did it get removed, or what? I can set the tuneable but I'd like to stick to the UI if the option exists.
