Install

Preparation ​

Enable japanese keyboard.

loadkeys jp106

Check if boot mode is UEFI.

ls /sys/firmware/efi/efivars

Ensure system clock is accurate.

timedatectl set-ntp true
timedatectl status  # Check

Installation ​

Partition the disks ​

Get a list of available disks.

parted -l  # OR lsblk -f

Start partitioning the desired disk. I prefer using parted.

parted /dev/nvme0n1  # fdisk /dev/nvme0n1

Here some partition tables I've used:

Number  Start   End     Size    File system       Name                  Flags

Format the partitions ​

Print the current partitions:

parted -l
lsblk -f

Mount the file system ​

/mnt will become the root of the new system.

Mount the root partition:

mount /dev/nvme0n1p3 /mnt

Mount other partitions:

mkdir /mnt/efi && mount /dev/nvme0n1p1 /mnt/efi
mkdir /mnt/home && mount /dev/nvme0n1p4 /mnt/home

Install the system ​

To speed up installation, update /etc/pacman.conf by enabling ParallelDownloads and [multilib]

ParallelDownloads = 5

[multilib]
Include = /etc/pacman.d/mirrorlist

To be on the safe side, update GPG keys:

pacman -Sy archlinux-keyring

Now use pacstrap to install the packages into the system.

xargs pacstrap /mnt < media/packages  # If batch installing
pacstrap /mnt base linux linux-firmware $ADD_MORE_HERE

• base-devel - Development packages
• networkmanager - Network connection manager and user applications
• grub efibootmgr os-prober - For boot
• neovim man-db man-pages - Basic tools

Configuration ​

Generate a default fstab file (using the current mount setup as base).

genfstab -U /mnt >> /mnt/etc/fstab

Login as root into the new system:

arch-chroot /mnt

Set the time zone:

ln -sf /usr/share/zoneinfo/Japan /etc/localtime
hwclock --systohc

Uncomment needed locales in /etc/locale.gen:

en_US.UTF-8 UTF-8
ja_JP.UTF-8 UTF-8

And run:

locale-gen

Set the keyboard layout in /etc/vconsole.conf:

KEYMAP=jp106

Set the network configuration:

• Set the hostname in /etc/hostname
• Add matching entries to /etc/hosts

127.0.0.1 localhost
::1       localhost

Set the root password:

passwd

Setup the boot loader (requires grub efibootmgr):

grub-install --target=x86_64-efi --efi-directory=/efi --bootloader-id=GRUB
grub-mkconfig -o /boot/grub/grub.cfg

The most basic configuration is done. Now you can exit and reboot.

exit
reboot

Post Install ​

As root ​

• Configure grub to support hibernation if going to use it
• Configure dm-crypt to unlock your partitions if using encryption
• Double check if /etc/fstab is correct
• Create and configure the new user

useradd -mG video,lp,wheel mateus
passwd mateus
usermod -s /usr/bin/fish mateus

• Give sudo permissions to users in wheel (run EDITOR=nvim visudo)

%wheel ALL=(ALL) ALL

• Give some extra permissions to users in wheel by editing /etc/security/limits.conf, if applicable

#<domain>      <type>  <item>         <value>
@wheel         -       nice           -5

• Enable some services

systemctl enable NetworkManager
systemctl enable greetd
systemctl enable paccache.timer

As user ​

Set the language.

localectl set-locale LANG=ja_JP.UTF-8

Import (and trust) your own GPG keys.

gpg -d gpg-master-keys.asc.gpg | gpg --import -
gpg --list-secret-keys --keyid-format short
gpg --edit-key KEYID
> trust

Restore password-store, ssh keys and other very basic stuff.

gpg -d keys.tar.zst.gpg | tar --zstd -x

Git clone repository with linux configuration, and apply configuration:

git clone git@github.com:Yutsuten/linux-config.git ~/.config/linux
cd ~/.config/linux
git submodule update --init
make
sudo make system

Set environment variables:

EDITOR=nvim sudo -e /etc/environment
# Copy contents of ~/.config/linux/system/env_vars

Add setvtrgb to HOOKS in /etc/mkinitcpio.conf, and run sudo mkinitcpio -p linux.

HOOKS=(base udev setvtrgb autodetect modconf block filesystems keyboard resume fsck)

Start/enable some user timers:

systemctl --user start/enable wallpaper.timer
systemctl --user start/enable trash.timer

Update pacman mirror list:

curl -s "https://archlinux.org/mirrorlist/?country=CN&country=JP&country=TW&protocol=https&ip_version=4&use_mirror_status=on" | \
  sed -e 's/^#Server/Server/' -e '/^#/d' | \
  sudo rankmirrors /etc/pacman.d/mirrorlist

Restore backup:

bkptool -r

Mostly that's it. For now on it's probably easier to continue as we have the basic stuff in place.
