I accidentally updated from 5.0 to 6.0 on 8.1.10 and wonder if it has any downfall. I have some legacy CentOS 6.10 pcts and from description of LXC 6.0, upstart support is removed. I am not sure how to interpret this change. I need to stick with 6.0 for some historical reasons on this box so I wonder if anyone have any thoughts.
