Closes #9054 There are two xattr packages in Python, pyxattr [1] and xattr [2]. They have different APIs. In old days pyxattr supports Linux only and xattr supports Linux, Mac, FreeBSD and Solaris, and pyxattr supports Linux only. Recently pyxattr adds support for Mac OS X. [3] An old version of [2] is shipped with Mac OS X. However, some Linux distributions have pyxattr only, for example PLD-Linux [4] and old Arch Linux. [5] As a result, supporting both is the way to go.
