Malo sem pobrskal po debianovih sourcih in dejansko so tele zadeve
popatchane:

/* Returns a pseudo-random number between 0 and 32767. */
static int
brand ()
{
#if defined(HAVE_RANDOM)
  return (unsigned int) (labs(random()) & 32767);
#else
  rseed = rseed * 1103515245 + 12345;
  return ((unsigned int)((rseed >> 16) & 32767));       /* was % 32768 */
#endif
}

/* Set the random number generator seed to SEED. */
static void
sbrand (seed)
     unsigned long seed;
{
#if defined(HAVE_SRANDOM)
  srandom(seed);
#else
  rseed = seed;
  last_random_value = 0;
#endif
}

Seveda debian uporablja random in srandom in ga zato tudi bash veselo
uporablja. Tako, da težava verjetno izvira od tam. 

A lahko še kdo s SuSEjem pogleda, kakšne source uporabljajo in kaj jim
piše v variables.c.
