The default package list in the merged change replaces dua with disktree-bin. A migration installs Disktree, removes dua, and deletes the old per-user Disk Usage launcher. The manual moves the entry from terminal tools to graphical ones and documents `disktree --disk` for a whole-disk scan.

David Heinemeier Hansson opened and merged the change. The pull request says Disktree was checked launching on a running desktop.
