Realistically, you won't need my wal config if you are not using my
bspwm setup, since wal does a good job at otherwise changing most other
color schemes that you may find in, e.g., a GNOME or Plasma setup.
Also, after some testing, it turns out that my previous assumption about
systemd was wrong. Placing a service in default.target.wants directly
will cause the service to instead not be recognized by systemd.
