As g4sra said, /run/user/xxx is used by session management and as you
say you have Xorg running on one of the machines, I guess someone is
logged in and running an X session. That would normally trigger
creation of /run/user/xxx.
BTW, /run/user/xxx is a tmpfs filesystem, i.e. it only exists in
memory. On my machine, I see
olaf@quark:~$ mount | grep /run/user/
none on /run/user/1000 type tmpfs (rw,relatime,mode=700,uid=1000)
olaf@quark:~$ find /run/user/
/run/user/
/run/user/1000
/run/user/1000/gnupg
/run/user/1000/gnupg/S.gpg-agent.ssh
/run/user/1000/gnupg/S.gpg-agent.browser
/run/user/1000/gnupg/S.gpg-agent.extra
/run/user/1000/gnupg/S.gpg-agent
which makes sense because `gpg-agent` is started as part of my Xfce4
session.
Hope this helps,
