Here is the link to the git repo which contains the pacman scripts for ArchLinux.
https://github.com/fosscafe/pacman-scripts
Each shell script can be used to install a group of packages.
Current scripts are focussed on:
1. networking tools
2. go lang
3. docker
The scripts in this repo will evolve through contributions and enhancements.
Hope this will help you complete the image you were trying to build.
Let me know if you face any issues.
warm regards
Saifi.
