Well where does the proxmox config come from in a vzdump? I assume it has to be in there somewhere? Looking further into it, other items need removing too which could be added to an excludes list in the tar command.

DAB does not meet my needs - I spend a lot of time installing software which is not in a repo and has to be manually installed. So are you saying that because there is nothing written down on OpenVZ, Proxmox will not support this feature? I basically want to create a template from an existing CT.
