Bug#789604: systemd-sysv: "halt" behaviour changed without notice

[Tom LAREDO]

Package: systemd-sysv
Version: 215-17+deb8u1
Severity: normal

Dear Maintainer,

The "halt" command behaviour has changed between Debian Wheezy and Debian
Jessie. On Wheezy (running sysvinit), when you run "halt", it stops OS and then disconnects
power. On Jessie (running systemd), it just stops OS and then hangs.
If you're on a virtual machine, you're able to see messages like: "Failed
to finalize DM device, ignoring" and "System halted" but the Virtual Machine just hangs with OS off and VM still running.

I took a look to the release notes and didn't notice anything about this
behaviour change.
The documentation seems not to make difference between using halt,
poweroff or shutdown -h now: https://www.debian.org/releases/jessie/i386/ch08s01.html.en

Please let me know if I miss something.

Best regards,
Tom LAREDO
