Arch Linux issues

Previously, Arch Linux did appear to suffer from more issues trying to make genie work than most distributions. This is a collection of solutions people have found:

libhostfxr.so not found

If Arch Linux is complaining about libhostfxr.so being not found when starting genie at boot, try the following:

1. yay -S dotnet-host-bin dotnet-runtime-bin dotnet-sdk-bin genie-systemd-git
2. create /etc/dotnet/install_location and put /opt/dotnet inside
3. change WSL startup command to wsl.exe ~ -d Arch genie -s
