systemctl enable bluetooth.service

# AutoEnable stays at its stock default on purpose. It was set to false here to
# persist the power state, which it never did: BlueZ has no such behaviour, so
# all it bought was Bluetooth coming up off on every boot. omarchy-bluetooth-power
# holds the state in the rfkill soft block instead, and leaving AutoEnable alone
# is what lets bluetoothd bring the adapter back up when that block is lifted.
