By default, if you specify -g in useradd that would be the primary group and is only stored in /etc/passwd. So, the solution is: useradd -g guix-builder -G guix-builder .... This will set the primary group in /etc/passwd and will also add the user in guix-builder group in /etc/group. You might not specify -g guix-builder which is OK, but it will generate an additional group for each user. Aleix
