Challenge accepted. Let's do it!
First things first, let's generate a list of all official Arch Linux packages. Fortunately, `pacman`, the best pragmatic package manager in existence, makes this a breeze.
```sh
pacman -Slq
```
Great, now let's install it all!
```sh
pacman -Slq | xargs sudo pacman -S
```
10 seconds later, you'll find yourself with... unresolvable package conflicts detected?
OK, fine, let's disable dependency checking then:
```sh
pacman -Slq | xargs sudo pacman -Sdd
```
Nope, didn't work. We have to do something about the conflicting packages!
## Time for some algorithms!
It's time to put our algorithms knowledge to good use. This is *just* a graph We can think of each package as a node in a graph
Since we don't care about making the dependencies all work out nicely, we just need to choose the larger package out of the two in each pair of conflicting packages. We have to give special treatment to `tensorflow`, `tensorflow-opt`, `tensorflow-cuda`, and `tensorflow-opt-cuda`, since they all conflict with each other, but we'll simply choose `tensorflow-opt-cuda` because it's the most bloated.
It's possible to programmatically do this, but that's left as an exercise to the reader. Plus:

Alright, time to install it all!
```sh
pacman -Slq | sed -E '/^(tensorflow|tensorflow-opt|tensorflow-cuda|python-tensorflow|python-tensorflow-opt|python-tensorflow-cuda|blas|python-h5py|python-gast|python-mistune|python-netcdf4|netcdf|python-pytorch|python-sqlalchemy|qtcurve-qt5|quassel-client|quassel-monolithic|racket-minimal|root|rssguard-nowebengine|srslte|tldr|ttf-nerd-fonts-symbols|vbam-sdl|vhba-module|virtualbox-guest-utils-nox|virtualbox-host-modules-arch|xarchiver|xrootd|yabause-gtk|zathura-pdf-poppler|lib32-pipewire-jack|wine|fcron|man-db|pipewire-jack|libreoffice-still.*|llvm11|msmtp-mta|perl-mail-spf|pipewire-media-session|exim|opensmtpd|nullmailer|plan9port|acpi_call-lts|broadcom-wl|clash)$/d' | xargs sudo pacman -Sdd --noconfirm
```
This is going to be *fun*:
