* Introduction
  :PROPERTIES:
  :CUSTOM_ID: h-12a4ef6d-13b6-4d1f-9e0f-a060b63b12d4
  :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: h-cfe21de6-15fa-477a-a5ff-6cd81dfead19
  :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 at least  two partitions, one
  dedicated to =/home=, the other to the root partition =/=.

  If the computer supports EFI bootloaders, the EFI partition will be mounted on
 =/boot=.  I generally  use rEFInd  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.

  The swap partition is always at least 4GB  large, and I should have a total of
  12GB of combined RAM  and swap. This means on my main computer  I have 16GB of
  RAM and 4GB of swap, but on my thinkpad I have 4GB of RAM and 8GB of swap.

** Get the latest live system with fast mirrors
   :PROPERTIES:
   :CUSTOM_ID: h-da7951ee-e39a-4a59-a05d-7b7fffdc7825
   :END:
   When you boot into the live ISO, execute the following command:
   #+BEGIN_SRC sh
     pacman -Sy reflector
     reflector -c France -c Germany -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.

** Install the system
   :PROPERTIES:
   :CUSTOM_ID: h-9f9e1fe5-4726-486b-9875-5fcfd91d0bb0
   :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.
   #+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.

* Install basic packages
  :PROPERTIES:
  :CUSTOM_ID: h-d2485595-3014-4151-a76c-63bc353359a8
  :END:
  We will need some basic packages in order to run the bootstrap file. So, let’s
  install =fish= (our shell running the script) and =git=.
  #+BEGIN_SRC sh
    yay -Sy fish git yadm
  #+END_SRC

* Execute bootstrap
  :PROPERTIES:
  :CUSTOM_ID: h-c13d132f-9e69-4bb0-838b-29c7c5611f11
  :HEADER-ARGS: :tangle ~/.config/yadm/bootstrap
  :HEADER-ARGS:python: :tangle no
  :END:
 =yadm=  comes with  a very  handy  feature: its  bootstrap script.  It can  be
  executed automatically once the dotfiles are cloned with yadm:
  #+BEGIN_SRC fish :tangle no
    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

  Notice these two header files, we can see  this is a fish script, hence why we
  need fish (which is my daily shell anyway).
  #+BEGIN_SRC fish
    #!/usr/bin/fish
    # -*- mode: fish -*-
  #+END_SRC
  Let’s take a look at what it does.

** Decrypt private yadm files
   :PROPERTIES:
   :CUSTOM_ID: h-2ce7e756-3dab-4c12-a3b3-d1b6f8d4805d
   :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
   yadm decrypt
   #+END_SRC

** Get a correct keyboard layout
   :PROPERTIES:
   :CUSTOM_ID: h-89fb8f3a-6ec4-4701-a5d9-3e593c47ece9
   :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,fr,us"
             Option "XkbModel" "pc104"
             Option "XkbVariant" "bepo,,"
             Option "XkbOptions" "grp:menu_toggle"
     EndSection'
   #+END_SRC
   So, let’s set it as our keyboard configuration.
   #+BEGIN_SRC fish
     printf "\n# Set keyboard layout #########################################################\n\n"
     echo $keyboardconf | sudo tee /etc/X11/xorg.conf.d/00-keyboard.conf
   #+END_SRC

** Set our locale
   :PROPERTIES:
   :CUSTOM_ID: h-48678405-93ae-41b6-b44b-285ab0da4e92
   :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
   Let’s enable these.
   #+BEGIN_SRC fish
     printf "\n# Set locale ##################################################################\n\n"
     for item in $mylocales
         if test (grep -e "#$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.
   #+BEGIN_SRC fish
     echo $localeconf | sudo tee /etc/locale.conf
   #+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: h-85ce90ff-56dc-469b-bf08-480ecf27acc4
   :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

   We also need the following folder for our nano backups.
   #+BEGIN_SRC fish
     mkdir -p $HOME/.cache/nano/backups
   #+END_SRC

** Set user’s shell to fish
   :PROPERTIES:
   :CUSTOM_ID: h-c1a78394-c156-4a03-ae82-e5e9d4090dab
   :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"
     if not test "$SHELL" = "/usr/bin/fish"
         chsh -s /usr/bin/fish
     end
   #+END_SRC

** Install =yay= if it isn’t already installed
   :PROPERTIES:
   :CUSTOM_ID: h-fef57cea-cf1d-4900-9d90-ec6353ea9661
   :END:
   Now we’ll need to be sure =yay=,  our AUR helper, is installed on our system.
   If it is, we  don’t need to to anything. However, if  it isn’t, we’ll install
   it manually.
   #+BEGIN_SRC fish
     if ! test (which yay)
         printf "\n# Installing yay ##############################################################\n\n"
         cd
         mkdir -p ~/fromGIT
         cd ~/fromGIT
         git clone https://aur.archlinux.org/yay.git
         cd yay
         makepkg -si --noconfirm
     else
         printf "\n# yay already installed #######################################################\n\n"
     end
   #+END_SRC

** Install basic packages
   :PROPERTIES:
   :CUSTOM_ID: h-887ec6d4-535d-4363-a0a7-884717b87a47

** Setting up Emacs: Installing Spacemacs

   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 ~/.config/emacs

   Now we can clone Spacemacs:
   #+BEGIN_SRC fish
     git clone --single-branch --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=

   For some reason, I  found installing directly this fork does  not work, and I

    Ly is a display manager based on ncurses  which I find nice enough for me to

    Thanks  to the  AUR  package ~nordvpn-bin~,  I no  longer  have to  manually

    Now let’s install =polybar-battery=. This is a binary that I’ll use in my [[file:.config/i3/config][i3
    config]] to  indicate my battery  level. It also  sends a notification  on low
    battery and on charging completed.

    When using rust, I bounce between two toolchains, the =stable= toolchain and

    #+BEGIN_SRC fish
      printf "\n# Install the rust toolchains, nightly is the default one #####################\n\n"
      rustup default nightly

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

    #+BEGIN_SRC fish
      printf "\n# Add rust utilities ##########################################################\n\n"

    We will also need some components for development purposes:
