Whether what I did might work for others may depend on the distro used and/or
whether or how plymouth is configured and/or installed. None of my installations
have plymouth installed except for Mageia, which is unusable if plymouth
installation is disallowed. In Mageia I include plymouth.enable=0 or noplymouth on
Grub's kernel cmdline and/or disable plymouth with systemctl.

For purposes of this thread, /etc/systemd/system/tdm.service did not exist. I
copied it from /lib/systemd/system/ and then modified it. IIRC, I was using
Bullseye only, not Buster as I wrote in OP.
