[systemd-devel] User wayland session, conceptual questions

[Vladimir Kudrya]

Hello again.

What would be the proper way of transferring environment variables set 
by pam for login sessions into systemd user service activation 
environment? Is there a tool or setting that does this automatically?

The problem is, in context of a login session it is hard to tell which 
vars were set by pam. Since those variables come from various pam 
modules for various applications (an example would be pam module for 
kwallet that sets PAM_KWALLET5_LOGIN), it is an open-ended list. I need 
to come up with a way to expose those vars to applications that are 
being launched as services in graphical session, but I would like to 
avoid just loading all the vars from login session context into 
activation environment.
