Using a drop-in instead of an extra service avoids having to juggle between both services (especially since irqbalance_mck did not have a Conflict=irqbalance.service statement) That way, we only have a single service to check for (irqbalance.service), and system administrators should find this less confusing if they normally rely on irqbalance. The drop-in is also installed in /run so will automatically disappear in the event of a linux crash or a reboot without shutting down mckernel Change-Id: I004f4f25d9ca037e411e0bc91f4555db138ecfef
