It is supported since the version aufs3.9 20141208. 9f0b20e 2014-12-07 aufs3.9 20141208 4ae64b4 2014-12-06 aufs standalone: new config XATTR 5ecf5fc 2014-12-06 aufs modular: new config XATTR ea0e18b 2014-12-06 aufs: xattr 10/10, config and build 470a400 2014-12-06 aufs: xattr 9/10, some filesystems don't list POSIX ACL ef6b594 2014-12-05 aufs: xattr 8/10, au_cpup_xattr() ae244b4 2014-12-05 aufs: xattr 7/10, branch attributes to ignore the error about xattr f24ae0c 2014-12-05 aufs: xattr 6/10, aufs_setxattr() and aufs_removexattr() acffe3e 2014-12-05 aufs: xattr 5/10, prepare au_pin_and_icpup() bbea82e 2014-12-05 aufs: xattr 4/10, make au_reval_for_attr() public 783be8d 2014-12-05 aufs: xattr 3/10, aufs_listxattr() and aufs_getxattr() 4a47bf2 2014-12-05 aufs: xattr 2/10, split aufs_getattr() 491ee29 2014-12-05 aufs: xattr 1/10, design document 5d15f18 2014-12-05 aufs: new options acl and noacl I don't know whether ubuntu people enables the necessary configutarion, but I'd suggest you to confirm these requirements. - CONFIG_AUFS_XATTR, CONFIG_FS_POSIX_ACL and a mount option 'acl' - branch fs has to support EA/XATTR too, obviously. - choose "icex" branch attributes in order to work the internal (copy,move)-(up,down) correctly.
