A last off-topic PS:

Around 2012, tar 1.26 didn't support extended attributes.

[root at archlinux rocketmouse]# systemd-nspawn -qD /mnt/q lsb_release -rc
Release:	12.10
Codename:	quantal
[root at archlinux rocketmouse]# systemd-nspawn -qD /mnt/q tar --version | head -1
tar (GNU tar) 1.26
[root at archlinux rocketmouse]# systemd-nspawn -qD /mnt/q tar --help | grep xattr | head -2 | tail -1
[root at archlinux rocketmouse]#

But tar version 1.27 provided by Ubuntu Trusty Tahr Ubuntu 14.04 LTS 
already supported archiving extended attributes:

http://manpages.ubuntu.com/manpages/trusty/man1/tar.1.html

So since around 2014, for around 6 years, tar has got extended attributes support.
