Dear Maintainer,

I have a new server running Debian Jessie, and when I reboot
it (e.g. due to kernel upgrade), it only halts. Last thing
on the screen is something like "systemd reached shutdown
target", and it newer reboots or shuts down.

I have this problem only on one of several new servers, and
the only difference I found is that this one uses nut to
monitor UPS. I suspect the file
/lib/systemd/system-shutdown/nutshutdown to have some bad
influence on the shutdown procedure. This problem may be
related to bugs #835555 and #835634, although this is a bit
different scenario. I do not really want to cut power on
UPS, I just want to reboot the server.

I think I did not notice it earlier as I had a watchdog
running (maually started). But it has a bug of its own, and
does not start automatically. Both seem like a bug with
systemd integration.

Thanks for any hints
Vladislav Kurz
