I tried to make it work without success -- result is unusable. So, one
of the issues - pam_systemd doesn't forward environment to child
process. Without that things like pam_gnome_keyring (probably) can work
only with awfull workarounds.

Second one is absence of "following" mode or so. So here is the problem:
login manager forks Xsession initialization and terminates the greeter
(and session) when it exits. If daemon running in background, some
waiting mechainsm should be invented. And again, new environment should
be propagated to shared instance (and if session stops, should be
deinitialized). So, to migrate, either some new daemon should be written
to do all that stuff, or dm managers should be reworked.

Do we really need such complexity?

Maybe old behavior can be offered as the option for those of us, who
really uses user session, at least till the moment, when mainstream will
be ready for migration? 

// Btw, there are some minor issues with proper
deinitialization|stopping -- PID 1 rests in timeouts while shutdown..
