The order of files in your ext4 filesystem does not matter
2025-04-06 the title is a cheeky reference to something at the front page of the orange site today1. i don’t want to be misleading here; glob order in bash is “alphanumeric”-ish.
this is more about documenting a wierd bug we encountered recently after a node image patch update, which in-turn caused a multi-hour outage since we could not get ahead of it in time. sidenote: containers use overlayfs and basically “stack” the image layers on top of one-another; and they use something called “white-outs” to handle deletion. fetching the tar blob, and replicating the containerd layer extraction logic (just the golang native"archive/tar" bits), the subsequent ls -1U output was basically the same, when running on the same nodepool.
