Subject: UPower ignores ‘critical-power-action’
Date: Tue, 30 Aug 2022 17:59:30 +0200

As discussed on IRC with Tobias, UPower appears to ignore our
‘critical-power-action’ setting.  On my machine, I left the default
(‘HybridSleep’) but upowerd dismisses it and chooses ‘PowerOff’:

Looking at the code, it could be because the ‘CanHybridSleep’ method
returns false, but why that would happen is unknown to me.

Thoughts?
