You’re going to have to quote that the stated problem was power outages. The first comment in this thread was taking about how the linked article solves the power outage problem.

But the sub-thread about using the existing utils is only for solving the unlock on reboot problem, and explicitly not solving the cold boot unlock problem.

First comment:

Even though I haven't checked, the "-delayminutes -1" very much sounds to me like it disables the automated reboot, so it waits until the machine reboots for other reasons. Given this and given that it is a direct reply, I personally took it as another solution to the power outage problem, the "reboot" in question actually being a cold boot due to the power outage.

Note that I haven't verified whether this works after removing power.
