WSL
Basic setup
Follow docs on Arch Wiki.
Create user
pacman -S sudo
useradd -m -g users -G wheel thomas
passwd thomas
Uncomment %wheel ALL=(ALL) ALL in /etc/sudoers.
Also add user to /etc/wsl.conf as specified in docs above.
Install yay
Install yay.
Also update /etc/makepkg.conf to remove debug from OPTIONS. Otherwise, we always install some debug packages.
SSH
Enable OpenSSH service (and auto-start) in Windows services.
Install wsl2-ssh-agent as described on Arch Wiki.
May also need to do ssh-add .../path on Windows for ssh-agent.exe.
