/usr/sbin/reboot: disabled in systemd-nspawn container

["sp007@caiway.net" <sp007@caiway.net>]

Hi,

Suddenly I can no longer reboot or poweroff my up-to-date
bullseye system:

# reboot
/usr/sbin/reboot: disabled in systemd-nspawn container

Linux container share the kernel of the host system they are running on,
there is no need to reboot just the container.

However, please contact your system administrator to reboot this
container from the host system.



# poweroff
/usr/sbin/poweroff: disabled in systemd-nspawn container

Linux container share the kernel of the host system they are running on,
there is no need to reboot just the container.

However, please contact your system administrator to reboot this
container from the host system.



I am definitively NOT in a container.

I did experiment with systemd-nspawn some weeks ago and stopped using
it.
I did often reboot/poweroff this system after this, and I have no idea
where to look for the bug.

# apt purge systemd-container does not help


Now I do Alt+SysReq+...to reboot/poweroff
