We can fiddle with PAM configurations (/etc/pam.d) to work around

Just a short note, partially related to this is that we have our
ongoing work of tlm (Tizen Login Manager) here:
https://github.com/01org/tlm
Did you consider that systemd will replace tlm, just like it claims to
replace the other session managers.
Since we are using systemd user session, it likely to ask systemd to as
the session manager too.
See http://lists.freedesktop.org/archives/dbus/2014-January/015927.html
As far as I can understand:
Login Manager != Session Manager
tlm would authenticate users and launche systemd as session manager, am
I wrong?
At the moment it handles TTY setup, PAM authentication flow and
bootstraps/ends the session as required by PAM. It can launch either
$SHELL, "systemd --user" or anything else as session. Our current
expectation is that it would launch "systemd --user" in Tizen, but it
can be configured to do something else too.
So you can think of tlm as headless version of login and/or *dm (it can
act in both roles). You can add GUI on top of it, but it is not
necessary. You can ask it to switch the user without having GUI
involved. It works in co-operation with systemd. The model is slightly
difference for Tizen compared traditional X dm's because with X the
Xserver is traditionally restarted between sessions but we expect to
support both models.
TLM is trying to keep some kind of session alive on all seats (queried
from systemd). Either with default (guest) user or some other specific
user as requested. When session is terminated it falls back to the
default "guest" login. So that is the main difference to *dm's - it
doesn't sit in a login prompt waiting for input. This is the behavior
defined for IVI and I'd expect mobile is also supposed to have a session
always alive, although TLM is not strictly necessary for mobile as long
as it is single user. But it could help solving some of the problems
discussed...
