![A screenshot of a terminal window showing that /nix/store is 109GiB uncompressed but only takes up 54GiB on disk (and has 233GiB data referenced). 30GiB of that data on disk is not compressed (64 GiB referenced) and the other 24GiB is zstd compressed (78GiB uncompressed, 169GiB referenced).
Command: `sudo xsz -j16 /nix/store`
