WSL

wsl-setup

WSL struggles with a startup delay for SystemD where it's not immediately ready when the WSL distro boots up. Consequently, the user services are not started at all automatically when starting the login shell.

See: nix-community/NixOS-WSL#375 (comment)

echo "Waiting for systemd..."
until systemctl &>/dev/null; do sleep 1; done

if ! systemctl --user &>/dev/null; then
    echo "Restarting user services..."
    sudo systemctl restart "user@$(id -u)"
fi

echo "Propagate WSLENV..."
systemctl --user set-environment WSLENV="$WSLENV"
