<pre>I have a Gentoo system with systemd set up. It's a laptop with multiple users.
When a user logs the first time they get a XDG_RUNTIME_DIR that is correct for
them. Then they log out, and another user logs in. That next user gets the
previous user's value for XDG_RUNTIME_DIR. That dir (/run/user/100x) is owned
by previous user and various services fail for next user.
The journal entries:
Mar 28 03:29:07 venus slim[8131]: pam_systemd(slim:session): Asking logind to
create session: uid=1003 pid=8131 service=slim type=x11 class=user seat=seat0
vtnr=7 tty= display=:0.0 remote=no remote_user=root remote_host=
Mar 28 03:29:07 venus slim[8131]: pam_systemd(slim:session): Reply from logind:
id=8 object_path=/org/freedesktop/login1/session/_38
runtime_path=/run/user/1000 session_fd=16 seat=seat0 vtnr=7
Which makes pam_systemd set XDG_RUNTIME_DIR to /run/user/1000, not the current
user's dir. Then:
Mar 28 03:29:07 venus gnome-keyring-daemon[8141]: couldn't create socket
directory: Permission denied
Notice the runtime_path is different from the uid that logged in. It's the
previous user.</pre>
