This should be written as: if ! systemctl enable --force $SERVICE 2>/dev/null; As written it should always fail.Please note that this snippet only works on systems that have a running systemd, thus it may fail when installing it in using debbootstrap, the debian installer, using a chroot, etc.
If possible, please tells us what have you tested. I'm also unsure of what would systemd do if you are replacing a running display-manager.service, we don't systemd to stop the running display-manager (as that's probably being used).
+ echo "WARNING: $SERVICE is the selected default display manager but does not have a systemd service" >&2
I see that the set of strings used by gdm sddm and lightdm are different. We should also sync those.
