I'm not sure we are talking about the same issue. In case of CrowdStrike, the update pushed a botched file that crashed the kernel on boot. Until the file was removed, the machine wouldn't even boot to be patched.

Yes, that's what I'm talking about.

I'm saying that in production, the screens and whatnot probably aren't fetching that file on boot, they're probably pulling from some central server. So in the case of an airport, each of those screens is probably pulling images from a local server over PXE, and the server pulls the updates from CrowdStrike. So once you get the server and images patched, you just power cycle all of the devices on the network and they're fixed.

So the impact would be a handful of servers in a local server rack, and then remote power cycle. If they're using POE kiosks (which they should be using), it's just a simple call to each of the switches to force them to re-PXE boot and pull down a new image. So you won't see IT people running around the airport, they'll be in the server room cycling servers and then sending power-cycle commands to each region of the airport.
