The bluetooth service is not started on boot. The issue is very similar to
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=734548, but the
bluetooth.target is active while the bluetooth.service is not.

I've enabled debug logs on systemd, and found a single line that seems wrong:
"systemd[1]: Trying to enqueue job bluetooth.target/start/fail". No reason
specified though (or I couldn't find one).

If I start the service manually (i.e. systemctl start bluetooth.service) then
everything starts working as expected.
Calling systemctl enable bluetooth.service doesn't seem to do anything (it
outputs 3 lines, as in [1])

Please let me know if I can provide any further output or feedback.

Thanks.

This was happening because of a dependency cycle in my system. Removing rpcbind
and nfs-common solved the issue.

Hi,

Thanks for your report.

I was confirmed in the Debian system minimal, but the problem you've
reported did not occur.

I installed these packages. However, bluetooth daemon has started successfully.

Best regards,
  Nobuhiro

Hi,

I had exactly the same problem ("bluetooth.service" dead after boot
although enabled, manual start of "bluetooth.service" is successful).
The dependency cycle might be caused by enabling
"|NetworkManager-wait-online.service|" (ref:
http://www.freedesktop.org/wiki/Software/systemd/NetworkTarget/, "How do
I make network.target work for me?").
After removal|("systemctl disable NetworkManager-wait-online.service|"),
"bluetooth.service" starts ok while booting.

Regards,
   Tilmann
