* 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 ~paru~ 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:
The first thing I will do is add the [[https://aur.chaotic.cx/][Chaotic AUR]] repository so I can
get access to ~paru~ as well as some AUR packages without the need of an
AUR helper (ironic considering ~paru~ is one).
#+BEGIN_SRC sh
sudo pacman-key --recv-key 3056513887B78AEB --keyserver keyserver.ubuntu.com
sudo pacman-key --lsign-key 3056513887B78AEB
sudo pacman -U 'https://cdn-mirror.chaotic.cx/chaotic-aur/chaotic-keyring.pkg.tar.zst' 'https://cdn-mirror.chaotic.cx/chaotic-aur/chaotic-mirrorlist.pkg.tar.zst'
printf '[chaotic-aur]\nServer = /etc/pacman.d/chaotic-mirrorlist\n' | sudo tee -a /etc/pacman.conf
#+END_SRC

I can now install ~fish~, ~git~, and ~paru~:
#+BEGIN_SRC sh
sudo pacman -S fish git paru
#+END_SRC

And now that ~paru~ is available, we can install ~yadm~:
#+BEGIN_SRC sh
paru -S 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_DK.UTF-8
LC_COLLATE=C
LC_NAME=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_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:

:END:

All these packages will be installed with the command ~paru -S
--skipreview --needed~ so it won’t nag me about the PKGBUILD when I
want to install something from the AUR, and if something is already
installed it paru won’t try to reinstall it.

** Tangle configuration files from Org files

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

:CUSTOM_ID: Execute_bootstrap-Set_up_dotfiles-ab372bd9
:END:
*** 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

I don’t want to activate it immediately however, since the first
startup might require some interactivity with the main Emacs frame,
not with emacsclient. When Emacs will be ready, its service can be
started like so (command not tangled in the bootstrap):
#+begin_src fish :tangle no
systemctl --user start 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"
    sudo systemctl enable --now sshd
end
#+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
nordvpn s protocol tcp
#+END_SRC

Note that this change in protocol is only valid when using the OpenVPN
technology. If we want to use the Wireguard technology through [[https://nordvpn.com/blog/nordlynx-protocol-wireguard/][Project
NordLynx]], this option will no longer be available. To set NordVPN to
use WireGuard, we can run this command (not tangled in the bootstrap).
#+begin_src fish :tangle no
nordvpn set technology NordLynx
#+end_src

Why WireGuard? Well, it can achieve better performances than OpenVPN
with physically nearby servers, and according to [[https://restoreprivacy.com/vpn/wireguard-vs-openvpn/][this article]] the
former can be more than half as fast as the latter. It is also much
more auditable than OpenVPN (only a few thousands lines of code
against some hundred of thousands). Oh, and WireGuard is part of the
Linux kernel since its version 5.6. And Windows’ since August 2021,
but I don’t really care about Windows.

*But*, WireGuard is less privacy-oriented than OpenVPN. So, if I ever
need to use my VPN for privacy reasons, I can simply revert back to
the OpenVPN technology like shown with this command (not tangled in
the bootstrap):
#+begin_src fish :tangle no
nordvpn set technology OpenVPN
#+end_src

Finally, I want to be notified of NordVPN’s actions, and I want to be
able to use IPv6.
#+begin_src fish
nordvpn set notify enabled
nordvpn set ipv6 enabled
#+end_src

** Symlink some system config files
:PROPERTIES:
:CUSTOM_ID: Execute_bootstrap-Symlink_some_system_config_files-1dd95175
:END:
Let’s 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 ~/.local/bin/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:emacs.org][Emacs config]] 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.

** 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
