If you can do shutdown that is fast & clean, why not do it always?

How fast is normal shutdown vs. fast shutdown?


I believe we should be more concrete here. Like explaining use (did
UPS say battery is low? Or does it mean 10 seconds remaining? Or...?)

Plus, who sets this flag? Userland?

Best regards,
