This command makes it easier to see what changed between two closures, i.e. what packages/versions got added or removed, and whether there were any notable changes in path size. For example: $ nix diff-closures /nix/var/nix/profiles/system-655-link /nix/var/nix/profiles/system-658-link blender-bin: 2.83.0 → 2.83.2, -294.2 KiB curl: 7.68.0 → 7.70.0, +19.1 KiB firmware-linux-nonfree: 2020-01-22 → 2020-05-19, +30827.7 KiB ibus: -21.8 KiB initrd-linux: 5.4.46 → 5.4.51, +16.9 KiB libexif: 0.6.21 → 0.6.22, +497.6 KiB linux: 5.4.46 → 5.4.51, +13.2 KiB mesa: 19.3.3 → 19.3.5, -183.9 KiB nix: 2.4pre20200701_6ff9aa8 → 2.4pre20200708_9223603, +9.7 KiB nix-bash-completions: 0.6.8 → ∅, -57.6 KiB nixos-system-hagbard: 20.03.20200615.a84b797 → 20.03.20200713.add5529 nvidia-persistenced: 440.82 → 440.100 nvidia-settings: 440.82 → 440.100 nvidia-x11: 440.82-5.4.46 → 440.100-5.4.51, +664.7 KiB pcre: 8.43 → 8.44 php: 7.3.16 → 7.3.20, -26.2 KiB python3.7-youtube-dl: 2020.06.06 → 2020.06.16.1, +8.4 KiB samba: 4.11.5 → 4.11.9, +30.1 KiB sane-backends: 1.0.28 → 1.0.30, +680.5 KiB source: -182.0 KiB zfs-kernel: 0.8.3-5.4.46 → 0.8.4-5.4.51, +9.9 KiB zfs-user: 0.8.3 → 0.8.4, +20.1 KiB
