minimal /\rch Linux installation starting right now
installation
configuration

installation

.Make bootable USB and Boot live environment

        sha256sum /directory/archlinux.iso
  • use either GUI-Utility like rufus and etcher or use dd to write your image_file to your USB-Flash-Drive
        dd if=/directory/archlinux.iso of=/dev/usb_flash_drive_file_name status=progress
  • boot your built Bootable-USB then select *Arch Linux install medium (x86_64, UEFI)

.Partition, Format, Mount and genfstab for your drive

  • create new partition for drive
    • use lsblk to know your Drive-Name first, then
    • use cfdisk TUI-Partition-Editor to open your Drive, then select GPT
    • then create Partition on your Drive as suggested as table below
Partition Mount on Size Purpose
/dev/your_drive_name1 /boot 256M minium for Kernel, Bootloader, EFI and Firmware
/dev/your_deive_name2 [SWAP] 512M minium for Swaping
/dev/your_drive_name3 / rest of drive for whole /\rch base

note: you can make [SWAP] partition as twice bigger as your Total-System-Memory-Size
use grep MemTotal /proc/meminfo to check your Total-System-Memory-Size
note: if you have Multiple-Fast-Drives, then create multiple smaller [SWAP] partitions on Multiple-Fast-Drives instead of using one giant [SWAP] partition on Single-Drive

  • format partions
        mkfs.fat -F 32 /dev/your_drive_name1
        mkswap /dev/your_drive_name2
        mkfs.ext4 /dev/your_drive_name3
  • mount partitions
        mount /dev/your_drive_name3 /mnt
        mount --mkdir /dev/your_drive_name1 /mnt/boot
        swapon /dev/your_drive_name2

note: the Order to mount your Partitions or Drives must obay the Hierarchy of File-System.
mount / Root-Partition to /mnt first, then mount Sub-Partition next, and so on

  • generate fstab ( File System TABle ) file
        mkdir /mnt/etc
        genfstab -U /mnt > /mnt/etc/fstab

.connect internet

--Just-Wire-In-->

.install Arch Linux

  • install essential packages
        pacstrap -K /mnt base linux linux-firmware sof-firmware amd-ucode networkmanager

base is minimal Arch_Base
linux is kernel. Arch_Base + Linux_Kernel = Arch_Linux
you can omit linux-firmware if you install Arch_Linux on VirtualBox
sof-firmware for some newer laptops to get Working-Audio, it's Optional for Minimal-System to get Working-Audio
amd-ucode provides AMD microcode. instead use intel-ucode if you use intel chip
you can omit networkmanager if you only use systemd [ o < ] to configure network
by this step, you can install other packages such as dust, btop, vim, tmux, calc, gcc, cmatrix, fastfetch, wget, transmission-cli, elinks, mpv and whatever you need

.install Bootloader and enable Microcode updates

  • write your Boot-Entry-File for Boot-Loader
        mkdir -P /mnt/boot/loader/entries
        vim /mnt/boot/loader/entries/arch.conf

example minimal Entry-File contents:

linux /vmlinuz-linux
initrd /amd-ucode.img
initrd /initramfs-linux.img
options root=UUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX rw

linux takes path to kernel; path is NOT /boot/... because we previously created partition for /boot
initrd initial ram disk; you need to load amd-ucode.img xor intel-ucode.img to RAM first before load initial-ram-file-system image
options takes Kernel-Parameters; replace UUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX to your own / Root-Partition-UUID;
which you can find it in previously generated fstab file, or you can run findmnt -n -o UUID / to show it

  • write your Systemd-Boot Config-File
        vim /mnt/boot/loader/loader.conf

example minimal Systemd-Boot Config-File contents:

default arch.conf
editor no

this set Default-Entry-File to previously wrote arch.conf, and no Boot-Entry-Editor.
you can write more Entry-Files with more Kernels than just one

  • install Systemd-Boot-Loader
        arch-chroot /mnt
        bootctl install

.finish the installation

  • set Root-Password
        passwd
  • reboot
        exit
        reboot

congratulation, minimal /\rch Linux is successfully installed.
you can login as root and configure your brand new /\rch Linux now

configuration

.user setup

  • set hostname
        echo 'your_new_hostname' > /etc/hostname
  • create Unpriviliged-User
        useradd -m your_user_name
        passwd user_name

remove all .bash* for this Unprivileged-User then switch to Unpriviliged-User and create .config directory

        rm -f /home/your_user_name/.bash*
        su -c "mkdir /home/your_user_name/.config" your_user_name

then add Unpriviliged-User to Secondary-Group audio,video,storage

        usermod -aG audio,video,storage your_user_name

and you can Remove entire /root directory and Make a Link-File of entire /home/your_user_name to /root

        rm -fr /root
        ln -s /home/your_user_name /root

.network

        systemctl enable NetworkManager
        systemctl restart NetworkManager
        nmtui

note: the Connection-Config-File generated by nmtui is placed at /etc/NetworkManager/system-connections

        pacman -Syu hblock
        hblock

you can manually update /etc/hosts file by run hblock again
or you can enable hblock.timer for Auto-Update

        systemctl enable hblock.timer

note: Thanks for Carter Li and other Related-Developers, Configuration like Above has been added to Official-Fastfetch-Exsamples
now you can directly test it by run fastfetch --load-config examples/22.jsonc along with trying out other developer's config too

add Below-Alias to /etc/bash.bashrc

alias fastfetch='ffsc="--load-config $HOME/.config/fastfetch/config_small.jsonc"; (( $COLUMNS > 128 )) && ffsc=""; fastfetch $ffsc'
alias clear='clear; command tput cup 4 0; fastfetch'

then you can use clear command as fastfetch.
you even can feed fastfetch --options to clear command
