As the command (-cmd ...) will run as root, perhaps it
could suspend the daemon by sending it a STOP signal.
When command is finished, it sends a CONT signal to
the daemon. The duration would effectively become
infinite.

amazing, you bought a UPS unit provides one minute of backup power!
take/send it back.

Assuming that the "shutdown command" calls initd with "init 0": why not
letting initd handle your database or whatever you want to terminate
cleanly prior to halting the system? Configured correctly with sufficient
timeouts init will wait for the application to terminate prior to moving
on for the next process.
It is has been mentioned previously that one has to distinguish between
initiating the shutdown and finally cutting power. The latter is an
internal function of the UPS and will depend on the size of the battery.
If the hardware can not provide for sufficient time to do a clean
shutdown it is not suitable for the application. As the battery degrades
in use an undersized UPS will become even more problematic over time.

you can keep saying it over and over ... but it is still incorrect.
The UPS is 1500VA / 900 watts. My load is 550 watts ... for about 15
to 18 minutes of battery power.

The issue is with the software from the vendor. I have spoken to them
to day and the confirmed the limitation around the runtime of the
scripts prior to shutdown. They will try to update the software.

In the meantime - I can use NUT, or try to add my script to the system
shutdown, return it for another make / model.
