Public bug reported: Yesterday, I had an issue with my Linux root file system. It had only 3 GB of 37 GB free, while the Disk Usage Analyzer told me there was only 10.3 GB of files stored in the partition. The AI told me it was incompatibility between the partition data and the file data inside the partition and none of the proposed AI remedies worked. So AI produced BS, because the program that checks and display file sizes the Disk Usage Analyser had a bug, it did not take into account a 20 GB VM-image that was stored in a very restricted root folder /var/lib/libvirt/images. When I forced the delete of the image file the problem was solved. To find the issue, I had to manually check the size of all folders, so now I detected three bugs:
1. Why did I have to do that manual check, AI should have done it. 2. The Disk Usage Analyzer did not check the size of the restricted folder, because it had been denied access and that is another bug. 3. Programs like virt-manager should not store the VM-Images by default in a restricted root folder. The home users or smaller companies might run into my type of problems. If needed the trained system administrators could still select /var/lib/libvirt/images, but for all others the default like that of boxes would be better ~/.local/share/gnome-boxes/images/. Aligning and moving the content of /var/lib/libvirt/ to ~/.local/share/gnome-boxes/ would anyhow create the advantage, that boxes-vms could be completed with the more advanced virt-manager functions. The final thought of my DeepSeek AI: Suggest virt-manager/boxes default to user-accessible paths. Your experience exposes real flaws in both AI-assisted troubleshooting and Linux UX design. While AI can provide general guidance, it often lacks context-awareness (like knowing you’re a VM user). Meanwhile, Linux tools need better defaults and transparency around permissions.
