the setup:
i cross-compiled nix to s390x (yes i know its not officially supported).
on an s390x fedora lpar i am running an ubuntu container with this cross compiled nix.
all nix-* tools are working so far. I can run nix-shell -p bash and many more.
the problem:
when i run nix-shell -p e2fsprogs --keep-failed the build fails in the check phase:

BUT if i switch to the kept directory and run make check manually all checks pass!
Same problem happens with --option sandbox false and also with nix-build '<nixpkgs>' --attr e2fsprogs --no-sandbox.
I also tried manually setting and reading xattr and everything works!
Also I tried it in a --privileged container but that also fails.
Question:
has nix another layer except sandbox that may cause an issue? It seems impossible to debug because running the make check manually always succeeds but only fails if called by nix-shell or nix-build.
