No user exists for uid when using ssh or whoami

[DCsunset]

Within nix-user-chroot ~/.nix bash, the program whoami and ssh stop working because it cannot find the user for the uid.

The uid doesn't change after running nix-user-chroot, but for some reason it can no longer find the user.

A similar issue is NixOS/nixpkgs#64665 but the solution no longer works since there's no libnss_sss.so.2 in my system.

I guess it is working similarly to the containers runtimes, and the uid inside nix-user-chroot shell doesn't match to the uid on the host, but there is a non-trivial mapping.

However, I'm also looking for an option to make ssh (and therefore Git operations based on SSH) working within nix-user-chroot.

I have run into this too. Especially with git.
Has anyone ran into a solution for it?

Any progress on this issue? It is really unfortunate that there is a powerful capability with nix and nix-portable to setup a dev environment in a sudo-less RHEL9 machine.... except that I can't do anything because ssh and other basic programs are crippled.

@NicolasRouquette consider that you should be able to just use even plain Nix without root access (since a couple of years, more or less), just choosing a different folder for your Nix store. Here a blog post about the topic
