When running Blue Hydra the syslog reflects numerous events as follows indicative /lib/udev/bluez-udev is not installed. For reference the version of Bluez installed is 5.47-1+b1
Of what I gather, it looks like bluez-udev was initially part of bluez 4.99, but was later removed with the update to 5.x. As a result, errors are occurring its removal
