./prepare.sh /dev/sda
  1. Install system and perform basic configuration:
./install.sh
  1. Configure initramfs to support encrypted btrfs root partition
sed -i '/^MODULES=()/ s/()/(btrfs)/' /etc/mkinitcpio.conf
sed -i '/^HOOKS=(/ s/filesystems/encrypt &/' /etc/mkinitcpio.conf
sed -i '/^HOOKS=(/ s/\s*fsck//' /etc/mkinitcpio.conf
mkinitcpio -p linux
  1. Add bootloader entry
CRYPTDEVICE_UUID=$(lsblk -o PARTLABEL,UUID | awk '/cryptroot/{print $2}')
efibootmgr --disk /dev/sda --part 1 --create \
           --label "Arch Linux" \
           --loader /vmlinuz-linux \
           --unicode "cryptdevice=UUID=$CRYPTDEVICE_UUID:cryptroot root=/dev/mapper/cryptroot rootflags=subvol=@ rw add_efi_memmap initrd=\initramfs-linux.img" \
           --verbose
