[SOLVED] systemd and bus missing on /run/user/1000

Hello,
on my Arch Linux system I'm experiencing a strange behavior where, after the installation of the system, I have correctly "bus=" file and "systemd" directory in "/run/user/1000", and, sometimes, after a reboot, they are missing. The missing of "bus" file does not allow me to call dbus correctly, while I guess that the missing of "systemd" directory does not allow me to run systemd services as the current user with UID=1000. I'm noting that systemd for root should work because by running "sudo systemctl status <servicename>" it works correctly.

$XDG_RUNTIME_DIR is correctly set to /run/user/1000

The content of "/etc/pam.d/system-login" is:

#%PAM-1.0

auth       required   pam_shells.so
auth       requisite  pam_nologin.so
auth       include    system-auth

account    required   pam_access.so
account    required   pam_nologin.so
account    include    system-auth

password   include    system-auth

session    optional   pam_loginuid.so
session    optional   pam_keyinit.so       force revoke
session    include    system-auth
session    optional   pam_motd.so
session    optional   pam_mail.so          dir=/var/spool/mail standard quiet
-session   optional   pam_systemd.so
session    required   pam_env.so

What is the process or command that at boot should create "bus" and "systemd" in /run/user/1000?
If these two file/directory are missing after a reboot, is there a way to generate them manually by a command?

They are/should be  created on login by pam_systemd, how or into what are you logging into?

I solved it. user@1000 service failed to start. When I started it by "sudo systemctl start user@1000" and then "bus" and "systemd" appeared again.

And why did it fail?

sometimes, after a reboot, they are missing

Suggests that this will happen again and pot. is some race condition you want to address?
