 This was to avoid listing the content and _only_ show the message.
 The message occurs with and without -d.

 The bug is that ls calls lpathconf() to identify ACL capabilities,
 fails on autofs and prints this as an error.

 Either autofs should learn the pathconf operation or ls should learn
 that the error EOPNOTSUPP for this operation should be handled silently.
