The impurity actually stems from syscalls like uname(2), which leak information about the underlying kernel. This breaks the Nix model because the kernel is not an explicit build input of user applications. There's no simple solution for this, I'm afraid. ptrace(2)? :-) Thanks, Ludo'. _______________________________________________ nix-dev mailing list [email protected] https://mail.cs.uu.nl/mailman/listinfo/nix-dev
