Description

From the attr(5) manpage:

       For  this reason, extended user attributes are only allowed for regular
       files and directories,  and  access  to  extended  user  attributes  is
       restricted  to the owner and to users with appropriate capabilities for
       directories with the sticky bit set (see the chmod(1) manual  page  for
       an explanation of Sticky Directories).
