I think this is because nix uses "getgrnam"
(nix/libstore/build.cc:472) which returns information only from
/etc/group not from /etc/passwd where the main group is stored. 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.
