  Or at least in Francios case it is. With arch, you have tdm.service to user
pure-systemd to manager tdm. The tdm.service file for Arch is:

$ cat ~/tde/pbpkg/tde-tdebase/tdm.service
[Unit]
Description=TDE Display Manager
After=systemd-user-sessions.service

[Service]
ExecStart=/opt/trinity/bin/tdm

[Install]
Alias=display-manager.service

  This is pure-systed. There is no wrapper script that ultimately launches some
wrapper with "exec something".

  In Francios setup on Mageia, that is exactly what happens. The Mageia service
file is:

cat prefdm.service
[Unit]
Description=Display Manager
After=livesys-late.service systemd-user-sessions.service

# On Mageia gdm/X11 is on tty1. We explicitly cancel the getty here to
# avoid any races around that.
# Do not stop plymouth, it is done in prefdm if required (or left to the dm)
Conflicts=getty@... plymouth-quit.service
After=getty@... plymouth-quit.service
OnFailure=display-manager-failure.service

[Service]
ExecStart=/etc/X11/prefdm -nodaemon
Restart=always
RestartSec=0
IgnoreSIGPIPE=no

  That service file does not launch a display manager, it calls the wrapper
script prefdm which essentially calls /etc/X11/lookupdm to get the name of the
display manager via (45TDE and 45TDE.conf) and then does:

preferred=`/etc/X11/lookupdm "$dm"`
[ -n "$preferred" ] && exec $preferred "$@" >/dev/null 2>&1 </dev/null

  That isn't systemd -- that is systemd-sysvcompat. That setup just relies on
getting "EXEC=/opt/trinity/bin/tdm" from 45TDE.conf and then launching it as an
init script.

  We need TDE to work with systemd.
