* Introduction
:PROPERTIES:
:CUSTOM_ID: Introduction-cd5792cd
:END:
Here will be presented what I do to get my system up and running on a fresh Arch Linux install. These installation instructions were written in order to get an Arch Linux distribution up and running with the same configuration as my main computer’s and my travelling laptop’s configuration.

* Install Arch Linux
:PROPERTIES:
:CUSTOM_ID: Install_Arch_Linux-ac7ad3b2
:END:
I usually install Arch from the [[https://www.archlinux.org/download/][vanilla ISO]], however I began using [[https://github.com/MatMoul/archfi][archfi]] to install easily the distro (I’ve done it so many times, I know how it works now). Usually, my distros will be installed on two partitions: ~/home~ and ~/~ (root).

If the computer supports EFI bootloaders, the EFI partition will be mounted on ~/boot/efi~. I generally use ~systemd-boot~ as my boot manager, but if you are more comfortable with another one, just install what you want. Be aware that if you format your ~/boot~ partition, you will delete all boot managers that already exist; so, if you are dual-booting, *DO NOT FORMAT IT*. Yes, I made the mistake of wiping the Windows boot manager when I used to dual-boot.

In order to use the ~suspend-then-hibernate~ systemd command, it is necessary to have a swap partition at least twice the size of your installed RAM. That is because when this command will be run, the system will try to save the current state of your machine, stored in your RAM, to the swap filesystem. If there is not enough space, the command will fail, and you won’t be able to use this command. For instance, my current computer has 32GB of RAM, hence my SWAP partition is 16GB large.

** Get the latest, fastest mirrors
:PROPERTIES:
:CUSTOM_ID: Install_Arch_Linux-Get_the_latest_fastest_mirrors-765401c9
:END:
When you boot into the live ISO, execute the following command:
#+BEGIN_SRC sh
  pacman -Sy reflector
  reflector -c FR -c DE -c BE -l 200 -p http -p https --sort rate \
            --save /etc/pacman.d/mirrorlist --verbose
#+END_SRC

This will update the packages from your live ISO, and you will get the best mirrors for your installation. Of course, change the countries accordingly to your location. In my case, I am only interested in French, German, and Belgian mirrors.

** Install the system
:PROPERTIES:
:CUSTOM_ID: Install_Arch_Linux-Install_the_system-3ff49aa6
:END:
Then you can use a custom script to ease your installation of Arch if you do not wish to do it manually. Personally, I’ve done it several times already, I know how the distro works, I just want to be able to install my distro quickly now. I’ll need to download the script with ~wget~, but apparently it isn’t installed by default on Arch ISOs anymore, so I’ll need to install it.
#+BEGIN_SRC sh
  pacman -S wget
#+END_SRC

Now, let’s grab the script. You can check it on [[https://github.com/matmoul/archfi][Github]].
#+BEGIN_SRC sh
  wget archfi.sf.net/archfi
  # Or from matmoul.github.io/archfi if SourceForge is down
  sh archfi
#+END_SRC

Then, follow the instructions and install Arch Linux. Take the opportunity to install as many packages as you need, mainly ~yay~ which I use as my package manager (it is just a wrapper for ~pacman~) and AUR helper, and ~pacman-contrib~ which will help us installing some packages later.

Once your system is installed, reboot and remove your installation media from your computer.

* Execute bootstrap
:PROPERTIES:
:HEADER-ARGS:fish: :tangle ~/.config/yadm/bootstrap :shebang "#!/usr/bin/fish" :exports code :mkdirp yes
:CUSTOM_ID: Execute_bootstrap-e37054ef
:END:
With the installation of Arch with ~archfi~, I will have [[https://github.com/Jguer/yay][yay]], an AUR helper, installed. This will allow me to have some basic packages installed in order to run the bootstrap described below. So, let’s install ~fish~ (our shell running the script), ~git~, and my dotfiles manager ~yadm~.
#+BEGIN_SRC sh
  yay -Sy fish git yadm
#+END_SRC

~yadm~ comes with a very handy feature: its bootstrap script. It can be executed automatically once the dotfiles are cloned with yadm:
#+BEGIN_SRC sh
  yadm clone https://labs.phundrak.com/phundrak/dotfiles
  # or if labs.phundrak.com is down or too slow for you
  #yadm clone https://github.com/phundrak/dotfiles
#+END_SRC

Let’s take a look at what it does.

** Decrypt private yadm files
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Decrypt_private_yadm_files-68af7157
:END:
Some private files are stored encrypted in the repository of my yadm dotfiles. I will need them later on during the bootstrap execution.
#+BEGIN_SRC fish
  if test "$USER" = 'phundrak'
      yadm decrypt
  else
      whiptail --yesno "Decrypt private files?" 8 40 && yadm decrypt
  end
#+END_SRC

** Get a correct keyboard layout
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Get_a_correct_keyboard_layout-77d24b30
:END:
I use mainly the [[https://bepo.fr/wiki/Accueil][bépo]] layout, a French keyboard layout inspired by Dvorak layouts, however I sometimes need to switch back to the standard French AZERTY or the American QWERTY layout, so I make it so the Menu key switches for me my layout between these three. This makes it so my xorg configuration of my keyboard looks like this:
#+BEGIN_SRC fish
  set keyboardconf \
  'Section "InputClass"
          Identifier "system-keyboard"
          MatchIsKeyboard "on"
          Option "XkbLayout" "fr"
          Option "XkbModel" "pc104"
          Option "XkbVariant" "bepo_afnor"
          Option "XkbOptions" "caps:ctrl_modifier"
  EndSection'
#+END_SRC

So, let’s ask the user if they want to set it as their keyboard configuration.
#+BEGIN_SRC fish
  printf "\n# Set keyboard layout #########################################################\n\n"
  whiptail --yesno "Would you like to set your keyboard layout to the bépo layout?" 8 55
  if test $status -eq 0
      echo $keyboardconf | sudo tee /etc/X11/xorg.conf.d/00-keyboard.conf
  end
#+END_SRC

** Set our locale
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Set_our_locale-e74d772a
:END:
I use two main locales, the French and US UTF-8 locales, and I like to keep the Japanese locale activated just in case.
#+BEGIN_SRC fish
  set mylocales "en_US.UTF-8 UTF-8" "fr_FR.UTF-8 UTF-8" "ja_JP.UTF-8 UTF-8"
#+END_SRC

I’ll let the user accept them one by one.
#+BEGIN_SRC fish
  printf "\n# Set locale ##################################################################\n\n"

  for item in $mylocales
      whiptail --yesno "Set the \"$item\" locale?" 8 40
      if test $status -eq 0 -a (grep -e "#$item" /etc/locale.gen)
          sudo sed -i "/$item/s/^#//g" /etc/locale.gen
      end
  end
#+END_SRC

This is my configuration I usually use when it comes to my locale.
#+BEGIN_SRC fish
  set localeconf "LANG=en_US.UTF-8
  LC_COLLATE=C
  LC_NAME=fr_FR.UTF-8
  LC_NUMERIC=fr_FR.UTF-8
  LC_IDENTIFICATION=fr_FR.UTF-8
  LC_TELEPHONE=fr_FR.UTF-8
  LC_MONETARY=fr_FR.UTF-8
  LC_PAPER=fr_FR.UTF-8
  LC_ADDRESS=fr_FR.UTF-8
  LC_TIME=fr_FR.UTF-8
  LC_MEASUREMENT=fr_FR.UTF-8"
#+END_SRC

Let’s set it as our system’s locale if the user whishes to.
#+BEGIN_SRC fish
  whiptail --yesno "Do you agree to have the following locale set?\n\n     $localeconf"  20 43
  if test $status -eq 0
      echo $localeconf | sudo tee /etc/locale.conf
  end
#+END_SRC

Now we can generate our locale!
#+BEGIN_SRC fish
  printf "\n# Generate locale #############################################################\n\n"
  sudo locale-gen
#+END_SRC

** Create some folders
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Create_some_folders-bf701387
:END:
Let’s create some folders we might need for mounting our drives, Android devices and CDs.
#+BEGIN_SRC fish
  printf "\n# Create directories for mounting #############################################\n\n"
  sudo mkdir -p /mnt/{USB,CD,Android}
  sudo chown $USER:(id -g $USER) /mnt/{USB,CD,Android}
#+END_SRC

** Set user’s shell to fish
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Set_user’s_shell_to_fish-1a794be2
:END:
First of all, the bootstrap shell will set the user’s shell to fish.
#+BEGIN_SRC fish
  printf "\n# Set fish as the default shell ###############################################\n\n"
  whiptail --yesno "Set the current user’s default shell to fish?" 8 50
  if test $status -eq 0 -a ! "$SHELL" = '/usr/bin/fish'
      chsh -s /usr/bin/fish
  end
#+END_SRC

** Install basic packages
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Install_basic_packages-17173316
:END:
Let’s set in a custom varible what packages we’ll be needing.
#+BEGIN_SRC fish

#+END_SRC

These are the minimum I would have in my own installation. You can edit it however you want. Let’s install those.
#+BEGIN_SRC fish
  printf "\n# Installing needed packages ##################################################\n\n"
  sudo pacman -Syu
  for pkg in $PACKAGES
      yay -S --needed $pkg
  end

** Tangle configuration files from Org files
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Tangle_configuration_files_from_Org_files-cc524361
:END:
Before tangling our configuration files, we need to create some directories first so our files can be properly tangled. Here’s the list of directories we need to create:
#+NAME: dirs-tangled-files

Our code to generate such directories looks like this:
#+BEGIN_SRC fish :noweb yes
  <<gen-dirs-tangle()>>
#+END_SRC

The next step is to tangle all the Org files. Here is the list of files that are to be tangled:

** Setting up Emacs: Installing Spacemacs
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Setting_up_Emacs:_Installing_Spacemacs-0b3d44b2
:END:
Now, the first thing we want to do with Emacs is install its Spacemacs distribution. We’ll clone its =develop= branch into =~/.config/emacs=. We need to do this prior to our dotfiles’ cloning because of some submodules that are cloned within our =~/.config/emacs= directory, and git won’t let us clone Spacemacs in an already existing and non-empty directory. To make sure it isn’t one, let’s delete any potentially existing =~/.config/emacs= directory:
#+BEGIN_SRC fish
  printf "\n# Installing Spacemacs ########################################################\n\n"
  rm -rf $HOME/.config/emacs $HOME/.emacs* .spacemacs
#+END_SRC

Now we can clone Spacemacs:
#+BEGIN_SRC fish
  git clone --branch develop https://github.com/syl20bnr/spacemacs ~/.config/emacs
#+END_SRC

And we can restore what might have been deleted in our =~/.emacs.d/private= directory:
#+BEGIN_SRC fish
  yadm checkout -- ~/.config/emacs/private/
#+END_SRC

** Set up dotfiles’ git repository
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Set_up_dotfiles-ab372bd9

*** Update our dotfiles’ remotes
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Set_up_dotfiles-Update_our_dotfiles’_remotes-5a0fe6f7
:END:
This line in the bootstrap script will test if the current user is using my username. If yes, it’s probably me.
#+BEGIN_SRC fish
  if test "$USER" = 'phundrak'
#+END_SRC

If it is me installing and using these dotfiles, I want the remotes of my dotfiles to be set to ssh remotes using my ssh keys.
#+BEGIN_SRC fish
  printf "\n# Update yadm’s remotes #######################################################\n\n"
  yadm remote set-url origin git@labs.phundrak.com:phundrak/dotfiles.git
  yadm remote add github git@github.com:phundrak/dotfiles.git
#+END_SRC

I will also want to decrypt my encrypted files, such as said ssh keys.
#+BEGIN_SRC fish
  printf "\n# Decrypt encrypted dotfiles ##################################################\n\n"
  yadm decrypt
#+END_SRC

Finally, let’s close this ~if~ statement.
#+BEGIN_SRC fish
  end
#+END_SRC

*** Update our submodules
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Set_up_dotfiles-Update_our_submodules-3e921579
:END:
Now we can download the various dependencies of our dotfiles. To do so, let’s run the following command:
#+BEGIN_SRC fish
  printf "\n# Getting yadm susbmodules ####################################################\n\n"
  yadm submodule update --init --recursive
#+END_SRC

** Enable some services
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Enable_some_services-3d38d98e
:END:
We have installed some packages which require some services to run. Let’s enable them.

*** Systemd-timesyncd
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Enable_some_services-Systemd-timesyncd-d887e45b
:END:
This service enables time syncing with the NTP protocol, so I can be sure my computer’s time is correct. The service first needs to be enabled:
#+BEGIN_SRC fish
  printf "\n# Enabling timesync ###########################################################\n\n"
  sudo systemctl enable --now systemd-timesyncd
#+END_SRC

Now, let systemd know I want to use the NTP protocol to keep my computer’s time synced.
#+BEGIN_SRC fish
  sudo timedatectl set-ntp true
#+END_SRC

*** Docker
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Enable_some_services-Docker-305e8309
:END:
First, let’s activate Docker on startup.
#+BEGIN_SRC fish
  printf "\n# Enabling and starting Docker ################################################\n\n"
  sudo systemctl enable --now docker
#+END_SRC

Now, if we wish it, we can be added to the =docker= group so we won’t have to type =sudo= each time we call Docker or Docker Compose.
#+BEGIN_SRC fish
  read --prompt "echo 'Do you wish to be added to the `docker` group? (Y/n): ' " -l adddockergroup
  if test $adddockergroup = 'y' || test $adddockergroup = "Y" || test $adddockergroup = ''
      sudo usermod -aG docker $USER
  end
#+END_SRC

*** Emacs
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Enable_some_services-Emacs-c7785c21
:END:
Emacs will run as a user service, which means it won’t be launched until we log in. However, the service won’t be started immediately, I personally prefer to start a standalone instance in which installing and compiling the Emacs packages will happen, and then once that is done I will start the service.
#+BEGIN_SRC fish
  printf "\n# Enabling Emacs as user service ##############################################\n\n"
  systemctl --user enable emacs
#+END_SRC

*** Mpd
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Enable_some_services-Mpd-f0f5b9b7
:END:
Mpd will also use as a user service in order to get rid of some lines of code in my configuration.
#+BEGIN_SRC fish
  printf "\n# Enabling Mpd as a user service ##############################################\n\n"
  mkdir -p ~/.config/mpd/playlists
  systemctl --user enable --now mpd
#+END_SRC

*** SSH server
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Enable_some_services-SSH_server-204f5997
:END:
Maybe we want to activate an SSH server on our machine. If so, we can enable it. Let’s ask the question.
#+BEGIN_SRC fish
  whiptail --yesno 'Do you want to activate the ssh server?' 8 50
  if test $status -eq 0
      printf "\n# Enabling ssh server #########################################################\n\n"

#+END_SRC

*** Ly
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Enable_some_services-Ly-f4b161c0
:END:
Ly is a display manager based on ncurses which I find nice enough for me to use (I generally don’t like using display managers). Let’s enable it, and let’s disable tty2 while we’re at it (Ly uses it to run X).
#+BEGIN_SRC fish
  sudo systemctl disable getty@tty2
  sudo systemctl enable --now ly
#+END_SRC

*** Acpilight
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Enable_some_services-Acpilight-39152794
:END:
~acpilight~ is our utility managing the brightness of our screen. There is actually no service to enable here, but we must ensure the user is part of the ~video~ group so we can modify the brightness of our screen without using ~sudo~.
#+BEGIN_SRC fish
  sudo usermod -aG video $USER
#+END_SRC

*** NordVPN
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Enable_some_services-NordVPN-75c1bd88
:END:
Thanks to the AUR package ~nordvpn-bin~, I no longer have to manually maintain my VPN connections with OpenVPN. However, it requires a service that we should activate:
#+BEGIN_SRC fish
  sudo systemctl enable --now nordvpnd
#+END_SRC

Let’s also set its default protocol to UDP. This will allow me to use any port while connected to any WiFi as long as the 443 port is available. Because yes, I do connect to a WiFi that blocks some important ports, such as the IMAP and SMTP ports. Thanks University of Paris 8 for being SO paranoid.
#+BEGIN_SRC fish

** Symlink some system config files

      set dest (echo $f | sed -n 's|^.*etc\(.*\)$|/etc\1|p')
      sudo ln -s $f $dest
  end
#+END_SRC

Let’s also symlink the ~plock~ script ([[file:bin.org::#Lock-635fcb38][source here]]) to ~/usr/bin~ so ~xss-lock~ can find it.
#+BEGIN_SRC fish
  sudo ln -s (which plock) /usr/bin/plock
#+END_SRC

** Install packages from git
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Install_packages_from_git-7c6a6ea4
:END:
Now, let’s install some packages from git directly.
#+BEGIN_SRC fish
  mkdir -p ~/fromGIT
#+END_SRC

*** Reveal.JS
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Install_packages_from_git-Reveal.JS-bb4da0bf
:END:
I sometimes use Reveal.JS to make presentations, and I set its location in my [[file:.spacemacs][dotspacemacs]] file to be in =~/fromGIT=, so let’s clone it there.
#+BEGIN_SRC fish
  printf "\n# Install Reveal.JS ###########################################################\n\n"
  cd ~/fromGIT
  git clone https://github.com/hakimel/reveal.js.git
#+END_SRC

** Install Rust
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Install_Rust-1839c4d0
:END:
*** Install the toolchains
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Install_Rust-Install_the_toolchains-3480764a
:END:
When using Rust, I bounce between two toolchains, the ~stable~ toolchain and the ~nightly~ toolchain, although I try to stick with Rust Stable. To install them, I will use ~rustup~ which has already been installed previously.
#+BEGIN_SRC fish
  printf "\n# Install the rust toolchains, nightly is the default one #####################\n\n"
  rustup default stable
#+END_SRC

This will both download the stable toolchain and set it as the default one. Now to install the nightly toolchain, let’s run this:
#+BEGIN_SRC fish
  rustup toolchain install nightly
#+END_SRC

*** Install some utilities
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Install_Rust-Install_some_utilities-c4a7c785
:END:
We’ll need some utilities when developing Rust from Emacs, namely ~rustfmt~ and ~racer~. Let’s install them with ~cargo~.
#+BEGIN_SRC fish
  printf "\n# Add rust utilities ##########################################################\n\n"
  cargo install rustfmt racer
#+END_SRC

We will also need some components for development purposes.
#+NAME: rust-components-table
| Component | Why                                         |
|-----------+---------------------------------------------|
| rust-src  | Rust documentation in Emacs                 |
| rls       | LSP backend for Emacs                       |
| clippy    | A better version of cargo’s ~check~ command |

#+NAME: rust-components-gen
#+BEGIN_SRC emacs-lisp :var components=rust-components-table[,0]
  (mapconcat (lambda (x) (format "rustup component add %s" x))
             components
             "\n")
#+END_SRC

#+RESULTS[b3935b1c09d86fe506b43670f52960306a1e9809]:
: rustup component add rust-src
: rustup component add rls

Here is the code to do so:
#+BEGIN_SRC fish :noweb yes
  <<rust-components-gen()>>
#+END_SRC

** Install some python packages
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Install_some_python_packages-a4447a6f

Some packages will be needed from pip in order to get our Emacs setup correctly working.
#+NAME: python-packages-table

: pip install --user python-language-server[all] pyls-isort pyls-mypy pyls-black

Let’s install them locally for our user.
#+BEGIN_SRC fish :noweb yes
  printf "\n# Installing Python packages ##################################################\n\n"
  <<python-packages-gen()>>
#+END_SRC

** Set up Chicken (Scheme interpreter/compiler)
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Set_up_Chicken_(Scheme_interpreter-compiler)-3c1a3c4a
:END:
Chicken needs to be set up before being used. First, we need to install its documentation.
#+BEGIN_SRC fish
  printf "\n# Setting up Chicken ##########################################################\n\n"
  chicken-install -s apropos chicken-doc
#+END_SRC

Then, we’ll complete the documentation like so:
#+BEGIN_SRC fish
  cd (chicken-csi -b -e "(import (chicken platform))" -p "(chicken-home)")
  curl https://3e8.org/pub/chicken-doc/chicken-doc-repo.tgz | sudo tar zx
#+END_SRC

** Set up our fish shell
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Set_up_our_fish_shell-f0741c22
:END:
The last thing we want to do is to set up our fish shell with some extensions in order to improve the user experience.

*** Install ~fisher~
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Set_up_our_fish_shell-Install_=fisher=-3a44531b
:END:
We will be using ~fisher~ as our extensions manager for Fish. Let’s install it.
#+BEGIN_SRC fish
  printf "\n# Installing fisher ###########################################################\n\n"
  curl https://git.io/fisher --create-dirs -sLo ~/.config/fish/functions/fisher.fish
#+END_SRC

*** Install our extensions
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Set_up_our_fish_shell-Install_our_extensions-188e4566
