The error message and its location in the source [1]:

  /* Map the header and all the administration data structures.  */
  p = mmap64 (NULL, total, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0);
  if (p == MAP_FAILED)
    {
      int errval = errno;
      unlink (fname);
      error (EXIT_FAILURE, errval, _("cannot map archive header"));
    }

... suggest that the problem is that localegen is trying to do a shared
writeable mmap.  These do not work on jffs2 [2].

I don't know the best way to proceed, but it would appear we need to
raise the issue with upstream.  It will not be fixed in jffs2.

That said, I am running debxo 0.3 base and not seeing the same error
messages.  (I see that the locale is set to "POSIX" immediately after
installation.)
