Bug#793198: systemd: poweroff, reboot without stopping services and unmounting

[Пронин Илья Сергеевич]

> Which version of systemd is that?

systemd 215
+PAM +AUDIT +SELINUX +IMA +SYSVINIT +LIBCRYPTSETUP +GCRYPT +ACL +XZ
-SECCOMP -APPARMOR

Package: systemd
Version: 215-17+deb8u1

> If you run "systemctl poweroff" or "systemctl reboot", does the

Yes, tested many times, just got "systemctl poweroff" leads to
filesystem corruption.

> Which commands exactly does LXDE use to shutdown/reboot?

Depends on environment, according to source "lxsession-logout.c", in
case of systemd is detected, lxsession-logout calls systemd's functions
through dbus: PowerOff, CanPowerOff, Reboot, etc.

> Which services are not stopped? Which mount points are not unmounted?

Shutdown log tells everything stopped and unmounted [ OK ]. Boot logs
attached with fsck report.

More details:

GRUB_CMDLINE_LINUX_DEFAULT="init=/bin/systemd systemd.log_level=debug
systemd.log_target=kmsg log_buf_len=1M enforcing=0"

BTW, my debian runs on external usb drive, maybe that's reason, but
it works without systemd. Please do not remove bug, problem still
exists.
