+PVE backport of tar
+To fix the PVE bug 928 
+we choose to do a backport of the Debian Stretch package, as this 
+bug is already fixed in 1.28-2.1 currently packaged for Stretch.
+This has the following advantage:
+ * we don't need to maintain a patch and a package ourselves, we
+ just need to rebuild
+ * due to the use of a special version string this package will 
+ be replaced by the original Debian one when doing a jessie-> stretch
+ upgrade. Hence we only need to keep this around until Stretch is release.
+To assure a smooth transition, we need to take a special care about
+the version. The chosen version string assures that we have a 
+higher priority than the buggy tar version, but a lower priority than
+any Debian release containing the fix.
+This is a list of current and expected tar versions sorted by dpkg descending
+priority (verified with dpkg --compare-versions) 
+1.28-2.1 : debian stretch version
+1.28-2.1~bpo80+1 : potential official backport
+1.28-3.1~bpo80pve+1 : our actualized backport (new backport from a new stretch version) 
+1.28-2.1~bpo80pve+2 : our fixed backport ( should not happen )
+1.28-2.1~bpo80pve+1 : our backport <------- we are here 
+1.27.1+pve.2 : our own old tar package
+1.27.1-2+b1 : jessie tar version
