I just realized that I haven't thought about having to defragment a disk in a really long time since it's been almost 10 years that I've used a Windows machine (that's not provided by work), as well as a machine that didn't have an SSD/NVMe for the boot disk. TIL this is indeed a thing for Linux. It would be really cool like other people said if it defragged a real disk, but also up the stakes by wiping your drive if you do it wrong or not fast enough (à la Suicide Linux). Though that's totally against the spirit of the game :)
