Displays reserved space as free space
Moving this from https://pagure.io/fedora-workstation/issue/101, look at how much space I have free on /home and /:
I noticed the display of free space is different than reported by nautilus and originally thought it was a nautilus bug, but nautilus agrees with df. Assuming df isn't broken, which seems safe, that means Disks is somehow wrong.
Disks reports my / is 75 GB (correct, assuming df rounds down to 74 GB and Disks rounds up) with 27 GB free, but actually I have 24 GB free, as reported by df (too big to be a rounding difference). It reports my /home is 924 GB (incorrect, df says 909 GB) with 687 GB free (incorrect, df says 641 GB free).
Notably, 687 GB is ~640 GiB, so if there's not some unit conversion error here, that would be an amazing coincidence. The result is as if the result were computed in GB, then converted from GiB to GB by mistake, given that the value was already in GB. So probably a bad unit conversation somewhere.
Here are my results from df in GB:
