Partionning

gdisk /dev/sda

o # create new gpt partition table
n # create new partition
# choose 550M for the size
# type 0xEF00 = efi system partition

# /boot has type 0x8300 (linux fs)
# / has type 0x8E00 (linux lvm)

LUKS setup (unencrypted /boot)

Check that correct kernel modules are loaded: lsmod | grep dm_crypt and lsmod | grep dm_mod.

# /dev/sda3 is the lvm partition
cryptsetup luksFormat -v -s 512 -h sha512 /dev/sda3
cryptsetup open /dev/sda3 luks_lvm

configure LVM

pvcreate /dev/mapper/luks_lvm
vgcreate arch /dev/mapper/luks_lvm
lvcreate -n swap -L 1G -C y arch
lvcreate -n root --extents 100%FREE arch

Format

mkfs.fat -F32 /dev/sda1 # efi partition
mkfs.ext4 -L boot /dev/sda2 # boot partition
mkswap /dev/mapper/arch-swap
mkfs.ext4 -L root /dev/mapper/arch-root

Mount partitions

swapon /dev/mapper/arch-swap
swapon -a ; swapon -s
mount /dev/mapper/arch-root /mnt
mkdir -p /mnt/boot
mount /dev/sda2 /mnt/boot
mkdir /mnt/boot/efi
mount /dev/sda1 /mnt/boot/efi

Install arch linux

Set /etc/pacman.d/mirrorlist correctly (closest mirrors on top) before proceeding.

pacstrap /mnt base base-devel linux linux-firmware grub efibootmgr vim networkmanager
genfstab -U /mnt >> /mnt/etc/fstab

Then arch-chroot /mnt /bin/bash and follow the user guide until next step.

Initramfs

Configure mkinitcpio for luks (https://wiki.archlinux.org/index.php/Dm-crypt/System_configuration#mkinitcpio). Add keyboard sd-vconsole sd-encrypt lvm2 to the HOOKS line in /etc/mkinitcpio.conf. keyboard should already be there. Also replace udev with systemd.

Grub

DEPRECATED now I use systemd-boot

Add to /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="quiet rd.luks.name=<DEVICE_UUID>=cryptlvm root=/dev/arch/root"

To get the device uuid: ls -al /dev/disk/by-uuid/. The DEVICE_UUID is for the luks partition (/dev/sda3 here). arch in root=/dev/arch/root refers to the volume group used by lvm.

Auto unlock luks encrypted partition (optional)

dd if=/dev/urandom of=/arch_luks_key.bin  bs=512 count=10
chmod 000 /arch_luks_key.bin
chmod 600 /boot/initramfs-linux*
cryptsetup luksAddKey /dev/sda3 /arch_luks_key.bin

And add that to /etc/mkinitcpio.conf: FILES=/arch_luks_key.bin.

Generate configs

mkinitcpio -p linux
grub-install --efi-directory=/boot/efi
grub-mkconfig -o /boot/grub/grub.cfg
grub-mkconfig -o /boot/efi/EFI/arch/grub.cfg

Cleanly reboot

Exit the chroot, unmount everything umount -R /mnt and reboot.

sudo setup

See this topic, need to add the following two things:

/etc/pam.d/nss-auth

#%PAM-1.0
session sufficient pam_unix.so
session sufficient pam_systemd_home.so
session required pam_deny.so

And add the following line (toward the end) in /etc/pam.d/system-auth

session    required                    pam_limits.so
session    substack                    nss-auth # <- THAT LINE!!!
session    required                    pam_unix.so
session    optional                    pam_permit.so

Install some softs

pacman -S zsh git tree neovim python-neovim htop fzf ripgrep alacritty fd hyperfine hexyl tokei and some fonts:

pacman -S noto-fonts noto-fonts-cjk noto-fonts-emoji noto-fonts-extra ttf-font-awesome ttf-inconsolata ttf-roboto

Create user

groupadd sudo useradd -m --groups sudo -s /bin/zsh greg

Misc stuff in userland

Keep wifi enabled

netctl list and netctl enable <profile-name>

GUI

Once gpu driver and xorg are installed:

pacman -S i3-wm rofi i3status-rust

For desktop display config:

#!/usr/bin/env bash

if $(xrandr --query | grep "HDMI-0 connected" 2>&1 > /dev/null)
then
  xrandr \
    --output VGA-0 --off \
    --output DVI-I-0 --off \
    --output HDMI-0 --auto --left-of DVI-I-1 \
    --output DVI-I-1 --primary --auto --rotate normal
else
  xrandr \
    --output VGA-0 --off \
    --output DVI-I-0 --off \
    --output HDMI-0 --off \
    --output DVI-1-1 --primary --auto --rotate normal
fi

Keyboard in xorg

To put under /etc/X11/xorg.conf.d/10-keyboard.conf.

Section "InputClass"
	Identifier "system-keyboard"
	MatchIsKeyboard "on"
	Option "XkbLayout" "fr,us"
	Option "XkbVariant" "bepo,"

	# the list of options is in /usr/share/X11/xkb/rules/base.lst
	Option "XkbOptions" "grp:alt_caps_toggle"
EndSection

SSH agent

See SO

In ~/.config/systemd/user/ssh-agent.service

[Unit]
Description=SSH key agent

[Service]
Type=forking
Environment=SSH_AUTH_SOCK=%t/ssh-agent.socket
ExecStart=/usr/bin/ssh-agent -a $SSH_AUTH_SOCK

[Install]
WantedBy=default.target

In ~/.pam_environment: SSH_AUTH_SOCK="$XDG_RUNTIME_DIR/ssh-agent.socket". Then systemctl --user enable ssh-agent, systemctl --user start ssh-agent. And in ~/.ssh/config, add the line AddKeysToAgent yes.

Chinese input method

See IBus. sudo pacman -S ibus ibus-libpinyin.

# in ~/.pam_environment

GTK_IM_MODULE=ibus
QT_IM_MODULE=ibus
XMODIFIERS=@im=ibus

Add ibus-daemon -drx to ~/.xinitrc.

Other softs

For things not packaged yet, or in aur.

  • aura from aur to install stuff from aur
  • bottom sudo aura -A bottom-bin a fancy htop
  • ripgrep-all cargo install --path . a wrapper around ripgrep to search in anything.
  • procs cargo install procs a fancy ps
  • zoxide smart cd command.
  • bat a cat clone with wings.
