This is sadly not my machine, which means I can not as easily test, and this might be due to a misconfiguration on his part, still, until we know what it is I thought it helpful to report here.

Not sure how user namespaces are used with nix, but I guess that it has something to do with the sandboxing. If I can provide additional tests for this issue, please let me know.

We tried the Determinate Nix installer afterwards - which didn't show that error and seemed to run through. But we also didn't get it to work, so perhaps it just didn't log the error correctly. Will look into that later again.

I don't have all the necessary context on WSL, so pardon me if I'm completely off the mark here; but is the systemd support enabled on the WSL? Is it WSL2?

This is some time ago, and the relevant engineer is on holidays till next year, so hard for me to answer now.

I believe it was wsl2, but I am not sure about systemd support.
