-** TODO [#A] Modify shell scripts in ~${PROJECT_ROOT}/zfs~ such that assumptions regarding avaialble datasets are minimized
-    - This could be done by softcoding dataset and pool names or creating functions that specify through argument
 ** TODO [#A] Create a ~${PROJECT_ROOT}/skel~ directory
     - Should contain a shell script setting new permanent but reversible XDG variables, copying the directory structure to existing user home directories, and setting it as default for newly created user home directories
     - Should contain subdirectories that match the paths relative to user home directories for XDG variables
