WSL does not use systemd by default.
According to this article, it systemd has been default on WSL Ubuntu since june 2023. https://learn.microsoft.com/en-us/windows/wsl/systemd
"Systemd is now the default for the current version of Ubuntu that will be installed using the wsl --install command default."
Also when I look in the /var/log/auth.log, there are many lines with systemd, e.g.:
Nov 25 22:30:14 ELCON45223 systemd-logind[155]: New session 6 of user velle.
Nov 25 22:30:14 ELCON45223 systemd: pam_unix(systemd-user:session): session opened for user velle(uid=1000) by (uid=0)
Nov 25 22:30:14 ELCON45223 systemd: pam_unix(systemd-user:session): session opened for user velle(uid=1000) by (uid=0)
Could someone please help me understand exactly which part creates this XDG_RUNTIME_DIR folder? Is it part of the systemd repo or not? And if the answer is (or may be) different between Ubuntu and WSL Ubuntu, I would be happy if you share what you know about any any of those cases :) Right now, I barely know where to report this issue.

WSL does not use systemd by default.
