: Partitioning
  1. gdisk /dev/sdX1 0xEF02
     gdisk /dev/sdX2 boot
     gdisk /dev/sdX3 LVM
  2. cryptsetup -c aes-xts-plain -y -s 512 luksFormat /dev/sdX3
  3. cryptsetup luksOpen /dev/sdX3 arch
  4. pvcreate /dev/mapper/arch
  5. vgcreate archvg /dev/mapper/arch
  6. lvcreate -L #G -n root
     lvcreate -l 100%FREE -n swap	 
  7. mkswap /dev/mapper/archvg-swap
	 swapon /dev/mapper/archvg-swap
	 mkfs.ext2 -L boot /dev/sdX2
     mkfs.ext4 -L root -m 0 /dev/mapper/archvg-root/root

: Mounting
  1. mount /dev/mapper/archvg-root/root /mnt
  2. mkdir /mnt/boot
     mount /dev/sda1 /mnt/boot

: Installation
  1. pacstrap /mnt base base-devel grub-bios
  2. genfstab -p /mnt >> /mnt/etc/fstab
  3. arch-chroot /mnt

: Configuration
  1. vi /etc/hostname
  2. vi /etc/vconsole.conf | KEYMAP="dvorak"
  3. vi /etc/locale.gen && locale-gen
  4. vi /etc/locale.conf | LANG="en_US.UTF-8"
                         | LC_COLLATE="C"
  5. ln -s /usr/share/zoneinfo/America/Los_Angeles /etc/localtime
  6. vi /etc/mkinitcpio.conf | HOOKS="...autodetect, keymap, encrypt, lvm2, filesystems..."
							 | MODULES="ext4, ext2"
  7. mkinitcpio -p linux     
  8. vi /etc/default/grub | APPEND root=/dev/mapper/archvg-root cryptdevice=/dev/sdX3:arch
	 grub-mkconfig -o /boot/grub/grub.cfg
  9. modprobe dm-mod
	 grub-install --target=i386-pc --recheck --debug /dev/sdX
	 if test ! -d /boot/grub/locale; then mkdir -p /boot/grub/locale; fi
	 cp /usr/share/locale/en\@quot/LC_MESSAGES/grub.mo /boot/grub/locale/en.mo

: Housekeeping
  1. exit
  2. umount /mnt/{boot,home,foo}
     umount /mnt
  3. reboot
