Instructions for setting up fresh Arch linux install

Arch Linux Guide

gpt format, with UEFI boot system and encrypted root

Notes

This will work for SD card instalaition as well as a standard install. To install on an SD card the boot and efi partitions must remain on the main hard drive. Replace /dev/sdX with /dev/mmcblk0 for the root partition using /dev/mmcblk0p1 in place of /dev/sdX3.

Partition Disk

• List all disk partitions fdisk -l
• make sure to check disk file type for gpt
• (Optional) clear disk drive shred --verbose --random-source=/dev/urandom --iterations=3 /dev/sdX
• Edit disk partition of choice cfdisk /dev/sdX

Partition	Size	Type	Use
/dev/sdX1	256MB	EFI System Partition	/boot/efi
/dev/sdX2	512MB	Linux filesystem	/boot
/dev/sdX3	8GB+	Linux filesystem	/

Configuring LUKS Encryption

• load dm-crypt modprobe dm-crypt
• load dm-mod modprobe dm-mod
• encrypt root cryptsetup luksFormat -v -s 512 -h sha512 /dev/sdX3
  • ... enter password x2
• open root as alias (luks_root) cryptsetup open /dev/sdX3 luks_root
• root now at /dev/mapper/luks_root

Format partitions

• format /boot/efi mkfs.vfat -n "EFI System Partition" /dev/sdX1
• format /boot mkfs.ext4 -L boot /dev/sdX2
• format / (root) mkfs.ext4 -L root /dev/mapper/luks_root

Mount partitions

• mount root to /mnt mount /dev/mapper/luks_root /mnt
• create /boot and mount
  • mkdir /mnt/boot
  • mount /dev/sdX2 /mnt/boot
• create and mount efi partition in /boot
  • mkdir /mnt/boot/efi
  • mount /dev/sdX1 /mnt/boot/efi

Install Arch Linux

• install to /mnt pacstrap -i /mnt base base-devel efibootmgr grub

Generate fstab file

• genfstab -U /mnt > /mnt/etc/fstab

Configure Arch Linux

System info

• chroot in arch-chroot /mnt

  • pacman -S os-prober ntfs-3g
  • os-prober
• edit grub nano /etc/default/grub
  • set GRUB_CMDLINE_LINUX="cryptdevice=/dev/sdx3:luks_root"
  • uncomment (#) GRUB_ENABLE_CRYPTODISK=y
  • ..save
• Now edit /etc/mkinitcpio.conf nano /etc/mkinitcpio.conf
  • add ext4 mmc_core mmc_block sdhci sdhci-pci to MODULES
  • In the HOOKS section, add encrypt and lvm2 after block
  • ...save
• generate initramfs mkinitcpio -p linux
• install GRUB grub-install --target=x86_64-efi --boot-directory=/boot --efi-directory=/boot/efi --bootloader-id=ArchLinux
• generate GRUB configuration grub-mkconfig -o /boot/grub/grub.cfg and grub-mkconfig -o /boot/efi/EFI/ArchLinux/grub.cfg

Close and reboot

• and then exit exit
• unmount all umount -R /mnt
• and reboot reboot
