  48 ************************************************
  49 WARNING: On this system, the built-in echo function of /bin/sh
  50 does not report failure when writing to a full device.
  51 To demonstrate, run this command:
  52
  53   /bin/sh -c 'echo hello > /dev/full; echo status=$?'
  54
  55 Notice that the failing echo leaves its exit status set to zero
  56 and does not produce a diagnostic.
  57
  58 That bug in /bin/sh would cause the test of the groups
  59 scripts to fail, so it is being removed from the list of
  60 programs checked by this test.
