  16 ************************************************
  17 WARNING: On this system, the built-in echo function of /bin/sh
  18 does not report failure when writing to a full device.
  19 To demonstrate, run this command:
  20
  21   /bin/sh -c 'echo hello > /dev/full; echo status=$?'
  22
  23 Notice that the failing echo leaves its exit status set to zero
  24 and does not produce a diagnostic.
  25
  26 That bug in /bin/sh would cause the tests of the nohup and groups
  27 scripts to fail, so those two are being removed from the list of
  28 programs checked by this test.
