Package: systemd
Version: 239-12~bpo9+1
Severity: normal
Tags: upstream
There is a way to get systemd to instantly reboot the system; this
behaviour is 100% reproducible if run on real hardware, i.e. not in
Qemu or similar. The cause is a misconfigured system, but this bug is
mainly about the lack of any diagnostics or journal messages of any
kind - the system instantly reboots without any message, even in
systemd debug mode.
Steps to reproduce:
1. Make sure nss-systemd is used in /etc/nsswitch.conf; i.e. that file
should contain this line:
passwd: compat systemd
2. Create a systemd generator script (i.e. an arbitrarily named
executable file in the /lib/systemd/system-generators directory),
containing only the following two lines:
#!/bin/sh
getent passwd > /dev/null
3. Run "sudo systemctl daemon-reload".
4. The system will reboot in a few seconds, without any journal
message or console output of any kind, even when running systemd in
debug mode.
Again, note that we have never been able to reproduce this reboot when
running an emulated system using Qemu, only when running on real
hardware. The bug has been reproduced on multiple different hardware
platforms.

With no further feedback and being unable to reproduce the issue, I'm
going to close this bug report as it is not actionable.
