One thing that was only mentioned briefly by someone else is the physical button turning on the computer.
Similar to the paperclip test figure out where the power button goes into the mainboardw and bridge that with a short cable. Is possible that by moving the case the old button lost a cable.
This is just one more thing to test though, it’s really trial and error as you know :)
No one forces unattended updates. And containerd is already living in the userspace.
If every dev would live on a kernel level stability approach we’d will not have a containerd release at all.
