+1, but as I mentioned in #47717, I think we'd want to have D-Bus
notifications sent by earlyoom to the desktop, so that a user knows
what's going on (especially since the earlyoom logs suck, it's not even
time stamped).

It's already configurable; I don't think Guix should go out of its way
to add non-free items to its default earlyoom configuration.
