> The purpose of the udev rule is to autostart the daemon when a device is attached and kill it on detach

@ahesford  _You are right_; we should not remove the udev_rule; without this _udev-rule_, the USB tethering won't work if I remove my device and plug it in again. I verified it by restoring the _39-usbmuxd.rules_ file from my system snapshot and everything was fine again. 
But the issue is this _udev-rule_ automatically runs `/usr/bin/usbmuxd` on boot, thus overriding the usbmuxd service, and nothing would work.

> In the absence of evidence that the systemd tag declaration actually causes a problem in the udev autostart rule, we should assume it takes no meaningful action and avoids carrying a patch for no purpose.

As evidence, killing this process `/usr/bin/usbmuxd` fixes everything.

So I would suggest that since this rule is required, you could edit the part of the rule that autostarts `/usr/bin/usbmuxd` on boot.
I have no knowledge about programming languages, so I have no idea about this.

Please patch this out, so this issue can be resolved; otherwise, I have to kill /usr/bin/usbmuxd every time on boot
Thank you
