Oops, I meant FTS_NSOK instead of FTS_NSOK. I think it would be safer
for dracut to do something like this since it is using FTS_NOSTAT:

    /* Get the file type if it could not be determined without stat.  */
    int info = fts_info;
    if (info == FTS_NSOK)
      {
        fts_set (fts, ent, FTS_AGAIN);
        fts_read (fts);
        info = ent->fts_info;
      }

I don't think it was ever safe to assume that fts_info would be set to
FTS_D (or another file type) when FTS_NOSTAT was used.
