### Description The Disk module produces **size-total** and **size-used** values, but not _**size-free**_. Can size-free please be added to the Disk module. ### Motivation I would like fastfetch to be able to fetch and display disk values equivalent to df. At present fastfetch provides Size and Used, but not Avail. ``` $ df -h / Filesystem Size Used Avail Use% Mounted on /dev/mapper/ubuntu--vg-ubuntu--lv 913G 625G 242G 73% / ``` ### Additional context _No response_
