Follow the instructions to perform the basic (opinionated) Arch Linux installation.
- Partition, encrypt, format, and mount the drive from the installation medium using prepare.sh script (replace /dev/sda with your drive):
./prepare.sh /dev/sda
- Install system and perform basic configuration:
./install.sh
- 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
- 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
