May I begin by thanking you for your work on this package. For some time I have been using Bluetooth PAN tethering, as described in this post. I installed busybox-power_1.21.1power1 after it was pushed to Extras. I found that Bluetooth PAN tethering no longer worked. I reverted to busybox-power_1.20.2power4, and found that Bluetooth PAN tethering worked again. Now that I know that the change is easily reversible, I would be happy to reinstall busybox-power_1.21.1power1 if I could be of any help in investigating the problem.
Once upstream BusyBox reaches 1.23.1, I'll update busybox-power and push that to extras-testing. Let's see if we can then get that version into extras . I'll drop a message once that has happened.
