I’ve read through that link and several other posts that I found on this forum… my newbie head is spinning.
I found a very recent thread here:
If I am reading it correctly, this person appears to have created a simple GUI (I read that as newbie friendly) program that should automate this process.
Would you recommend using this or using this from the link you provided:
- pacdiff-pacman-hook-git — Pacman hook to run pacdiff automatically.
 
GitHub - desbma/pacman-hooks: Arch Linux Pacman hooks || pacdiff-pacman-hook-gitAUR
Or something else?
