That might be nice... but, how come your services register a logind session in the first place? That doesn't happen unless something deliberately calls pam_systemd – and the service startup process generally doesn't involve calling PAM in the first place. So something doesn't add up. (Are you using su?) (GDM is an exception – the service is not in a logind session, but the login screen (greeter) *is*, and it might rely on user@ being available just like a regular GNOME session.) <div class="gmail_quote"><div dir="ltr">On Tue, May 9, 2017, 18:09 Jakob Schürz <<a href="mailto:wertstoffe@nurfuerspam.de">wertstoffe@nurfuerspam.de</a>> wrote: </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi There! I have two services running in systemd --user, which should only be startet for login-users. If i put the service-file by a deb-package in /usr/lib/systemd/user, the service will also be started for Debian-exim, Debian-gdm and other users with a UID below 1000. And this is not "good"... Is there a mechanism in systemd --user to start services only for UIDs > 1000 (on Debian... other Distros may have the first login-user with UID=500... how can i catch this?) Or is it possible, to start Units only, if the user is in a special unix-group? For example a group called "cups-fuse" or "backup", then the service is startet in the users systemd only, if the user is in this group. For now i have a [Service] ExecStartPre=/bin/sh -c '/usr/bin/test %U -ge 1000' This produces a failed unit... That is not "beautiful" and leads to wrong thoughts, watching the journal. I need this services really only for logged in real users. Not Debian-gdm or Debian-exim. And i need a solution, to activate it per package-installation automatically for all the users who should be able to login... Maybe a Condition for a set usershell or another item, which identifies a user as a login-user...
