What is wrong with su ? su pam service file is including "common-session" which is by default (well when the module is installed) calling pam_systemd module which is starting a logind user session. Non-interactive process shouldn't call "common-session" but should call "common-session-noninteractive" (which is not including pam_systemd) but this is not possible with su. runuser is not using "common-session" and seems more fit to change user when run by non interactive process, the manpage state: "runuser allows to run commands with substitute user and group ID." While su manpage explicitly mentions a login session: "The su command is used to become another user during a login session." > > > Could you please adjust /etc/cron.daily/popularity-contest to call > > this new command?

Well I guess it's needed to have a versioned dependency to be sure that the util-linux package is containing runuser command which is not part of the current stable release.
