Hi,
Even after enabling and starting the service, it doesn't start
automatically on the next reboot. Manually executing
# systemctl start bluetooth.service
Indeed starts the service. My temporary solution to avoid that, was to
copy /lib/systemd/system/bluetooth.service into the /etc/systemd/system
directory, modify the service so that it's wanted by the
multi-user.target and create a relative symlink in the
multi-user.target.wants directory.
It seems to be a configuration problem, or a conflict between the
bluetooth.service and bluetooth.target units.
