I remember Debian had an oddly restrictive policy for systemd bus access (though it seems to be fixed now?). <div class="gmail_quote"><div dir="ltr">On Mon, Nov 23, 2015, 14:24 Andrei Borzenkov <<a href="mailto:arvidjaar@gmail.com">arvidjaar@gmail.com</a>> wrote: </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">On Mon, Nov 23, 2015 at 11:00 AM, <a href="mailto:yankun@iscas.ac.cn" target="_blank">yankun@iscas.ac.cn</a> <<a href="mailto:yankun@iscas.ac.cn" target="_blank">yankun@iscas.ac.cn</a>> wrote: > > what is the relationship between systemd-logind and polkit.Because when I do > like this "systemd-analyze plot ",it tells me that "failed to list > units:Access denied".About this ,I have no idea. It's not related to logind; this is answered directly by systemd and actually should not require any authentication (nor does systemd call polkit for ListUnits). I can only imagine that your D-Bus policy blocks it. Are you doing it as root? _______________________________________________ systemd-devel mailing list <a href="mailto:systemd-devel@lists.freedesktop.org" target="_blank">systemd-devel@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/systemd-devel" rel="noreferrer" target="_blank">http://lists.freedesktop.org/mailman/listinfo/systemd-devel</a> </blockquote></div>
