## Install all required packages for this user. It only needs to be run once
## when setting up the HOME directory.
##
## This script is designed not to ask the user over and over again for their
## sudo password. Since it uses yay and makepkg to install AUR and custom
## PKGBUILDs, the somewhat hacky way to do this is as follows:'
## 1. call this script as root
## 2. give the nobody user permission to run pacman with no password via sudo
## 3. set up a custom, temporary HOME directory for yay which is owned by nobody
## 4. run yay as nobody with HOME set to the directory made in (3)
## 5. run makepkg as nobody
## 6. remove the temporary HOME for yay
## 7. remove the pacman sudo privilege for nobody
