This is ultimately not very productive, but I've had free time lately for obvious worldly reasons.
I feel as if I'm missing something obvious, but is there any way to completely remove a package and its directories through pacman without running
rm -rf /path/to/directory]
manually after
pacman -Rs package_name
and hoping you get everything?
Otherwise, my best solution so far has been to run
tree
with options where I can browse through my directories and check file-by-file.
I've unintentionally developed a neurosis where I want my system as clean as possible since I've put enough time into it. Which may be dumb, but yeah.
