Hi Jules, I got similar problem with you, the systemd-shim is trying to execute '/sbin/poweroff', but I don't know why.
here's my backtrace using pstree(replace your 'ps ax -H' with 'pstree'). At first dbus-daeom forks systemd-shim, then it leverages systemd-shim to perform the poweroff. |-dbus-daemon --system --fork | `-dbus-daemon --system --fork | `-systemd-shim /usr/lib/x86_64-linux-gnu/systemd-shim | `-pstree -a |-systemd-shim | |-sh -c /sbin/poweroff | | `-shutdown /sbin/shutdown -h -P now | | `-pstree -a Well, I'm quite confused about it, who want to kill the system? I'm using Ubuntu 14.04 LTS and systemd-shim version 6-2bzr1, on linux 4.1-rc3 x86_64 Best Regards, Yu -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
