[Nut-upsuser] upsmon shutdown based on Time since power fail.

[Richard Chapman]

Thanks Jon

This sounds like one way to do it. If I do it this way - do you know 
whether the file:

/etc/killpower

will be created before the shut-down is issued (as it would if the 
battery low event occurs). If not - the UPS may not be shut down - and 
therefore the system may not start up again if the power returns before 
the battery is completely flat.

I guess if the flag file isn't created - then we could run a short 
script to create it - then issue the shut-down.... Does that sound right 
to you? Indeed - if we do write a short script - we could do the delay 
in the script - somehow test whether we are still on battery - and if so 
- issue the shut-down immediately.

Out of interest - do you know what the ups parameter:

battery.runtime: 120

Means - and where might it be documented?

Thanks Jon


Richard.
