Override systemd service in /usr

General
1

I am trying to edit the systemd unit that starts Gnome on login.

I believe I have located the unit under /user/lib/systemd/user/org.gnome.Shell@wayland.service and tried to edit it, but:

> ls /usr/lib/systemd/user/org.gnome.Shell@wayland.service
'/usr/lib/systemd/user/org.gnome.Shell@wayland.service'

> sudo systemctl edit org.gnome.Shell@wayland.service
No files found for org.gnome.Shell@wayland.service.
Run 'systemctl edit --force --full org.gnome.Shell@wayland.service' to create a new unit.

Why is this “not found”? Should this not create an override under /etc/systemd that “replaced” the immutable one in /usr ?

How can I achieve what I need?

If its a user service, you need to specify --user otherwise it will search for a system wide service file.

So this would probably do what you want
systemctl edit --user org.gnome.Shell@wayland.service
