      # for syscalls with 'errno', the error number is positive, and sign-flipped
      # for the return from the kernel. glibc then provides access to the errno
      # as the flipped result of the last failed system call.
      #
      # because some system calls use errno and some do not, we can't generically
      # deal with this, so we require each syscall chaos config to explicitly provide
      # the ret code and not the error code.
      #
      # you can consult the man page for the system calls for this - e.g. here's
      # openat --> https://manpages.debian.org/unstable/manpages-dev/openat.2.en.html
