plymouth-quit-wait will simply hang until plymouth quits of it's own
accrord. If you actively quit plymouth first via plymouth-quit then
there is literally no point in running plymouth-quit-wait as it'll just
exit immediately.

Also u're forgetting about the Conflicts= directives...

display-manager.service:Conflicts=getty at tty1.service plymouth-quit.service

display-manager specifically conflicts with plymouth-quit.service (as it
internally quits plymouth or allows a smooth transition if appropriate).

So the ordering is correct as it stands.

Now the question is what is preventing plymouth from being quit? As I
said, display-manager should do it for you (see the /etc/X11/prefdm
script), or simply let GDM do it itself.

I'll see what I can dig up.
