Package: exim4-base Version: 4.89-2+deb9u1 Severity: normal Dear Maintainer,
I have some systemd --user services from other packages. The units are located in /etc/systemd/user/ or /usr/lib/systemd/user/ and enabled on installing. When a daemon uses su or sudo on debian, it starts a service user@$UID.service which is a systemd-daemon for the user-session. This sessions are normally not started for Daemons with UID below 1000 (except Debian-gdm). I asked on the systemd-mailinglist, whats the problem, because sometimes exim starts an user-session (and with this the user-services which are thought for login-users with UID greater-equal 1000). They told me, there must be the use of su or sudo in some scripts from the daemon. I looked around and found, that there is su used in /etc/cron.daily/exim4-base You find my changes below to use runuser instead of su, which solves the problems comming from the su-command.
