[Bug 1313550] Re: ping does not work as a normal user on trusty tarball cloud images.

[Scott Moser]

This would seem straight forward enough (I thought I could just add '--
xattrs' to both creation and extraction of tar), but that doesn't seem
to look.  See the attachment, and its output here, it seems that tar is
losing these.

$ sudo /tmp/xattr-save-ping 
$ ls -l /bin/ping
-rwxr-xr-x 1 root root 44168 Mar 15 02:24 /bin/ping
$ attr -l /bin/ping
Attribute "capability" has a 20 byte value for /bin/ping
$ tar -C / --xattrs -Scpf - bin/ping | tar -C $tmpd --xattrs -Sxpf -
$ ( cd $tmpd && attr -l bin/ping )
$ ( cd $tmpd && attr -l ping_rsync )
Attribute "capability" has a 20 byte value for ping_rsync

So, above, it seems like bin/ping that was created by tar did not get
the attr laid down.
