Simple, modern and secure installation of Arch Linux with KDE Plasma.

This is my personal installation routine, which I continously expand and redefine.

This installation script aims for a simple (read minimal) Arch Linux installation, which is modern in the way that it uses UEFI, systemd-boot and Wayland, secure in the way that it uses full-disk encryption using LUKS as well as flexibility by using Btrfs subvolumes for the root and home partition.

Click here to go to the manual installation (legacy Ext4/LVM)...

To automatically install Arch Linux, clone this repository:

# pacman -Sy git
$ git clone https://gitlab.com/dataprolet/arch
$ cd arch
$ sh install.sh

Or as a one-liner:

# pacman -Sy git --noconfirm && git clone https://gitlab.com/dataprolet/arch && cd arch && sh install.sh

• Tested and working as of August 2023.

To switch from X11 to Wayland on an existing installation use the following command and reboot:

# pacman -S wayland xorg-xwayland plasma-wayland-session && sed -i 's/plasma/plasmawayland/g' /etc/sddm.conf.d/kde_settings.conf

### *There are now two additional versions of the script:*
- `install-lvm.sh` - Installs using Ext4 and uses LVM for /root and /home.
- `install-grub.sh` - Installs using GRUB for legacy BIOS.

## All features:
- Prompt for all user input at the start (hostname, username, passwords).
- Partitions a primary and a boot partition.
- Encrypts the primary partition using LUKS.
- Creates Btrfs filesystems with zstd compression.
- Creates Btrfs volumes for /root and /home.
- Refreshes the latest mirror list.
- Installs a base system (base linux linux-firmware btrfs-progs nano networkmanager sudo).
- Installs very few additional packages (firefox konsole linux-zen)
- Installs a minimal KDE Plasma desktop environment (plasma-desktop, sddm, sdmd-kcm)
- Installs systemd-boot as a bootloader.
- Sets German keyboard layout and English locale.
- Enables SDDM auto-login to boot into Plasma after the first reboot.
