* Package Management
** Arch and AUR Packages
*** Package Manager
General Package Management is done via [[https://github.com/Jguer/yay][Yay]].
~update.sh~ will install it if needed.
#+begin_src shell :tangle update.sh
if ! command -v yay &> /dev/null
then
    echo "Installing Yay ..."
    pacman -S --needed git base-devel
    git clone https://aur.archlinux.org/yay.git
    cd yay
    makepkg -si
fi
#+end_src

*** Package Installation
remove all packages not in ~pkg-list.txt~
#+begin_src shell :tangle update.sh
# Get list of installed packages
INSTALLED_PACKAGES=$(yay -Qqe)

# Read the list of packages to keep from the file
KEEP_LIST=$(cat "pkg-list.txt")

# Loop through installed packages
for PACKAGE in $INSTALLED_PACKAGES; do
    # Check if the package is not in the keep list
    if ! echo "$KEEP_LIST" | grep -q "^$PACKAGE$"; then
        echo "Removing package: $PACKAGE"
        # Uncomment the following line to actually remove the package
        yay -Rns --noconfirm "$PACKAGE"
    fi
done
#+end_src
and install the packages specified in ~pkg-list.txt~
#+begin_src shell :tangle update.sh
yay -S --needed `grep -v '^#' pkg-list.txt`
#+end_src


* Base System
** Arch Linux
the following packages are required for basic operation and should never be deleted
#+begin_src shell :tangle pkg-list.txt
amd-ucode
base
efibootmgr
grub
linux-zen
linux-lts
linux-firmware
lvm2
sudo
#+end_src

** Networking
This config uses the [[https://wiki.archlinux.org/title/NetworkManager][NetworkManager]]
#+begin_src shell :tangle pkg-list.txt
networkmanager
#+end_src
after being installed it also needs to be enabled
#+begin_src shell :tangle update.sh
systemd_service="NetworkManager"
if ! systemctl is-enabled --quiet "$systemd_service"; then
    echo "Enabling $systemd_service"
    sudo systemctl enable "$systemd_service"
    sudo systemctl start "$systemd_service"
fi
#+end_src
