Hi Bernard, looks good. But I believe you're missing config files of the OSCAR applications like netbootmgr (files are also in /tftpboot), torque, maui, ganglia, ... These are not only config files, but also files referred by config files (for netbootmgr: the files in /tftpboot/...).
While we could detect config files from the RPMs automatically (those marked as %config in the .spec), the files refered by them cannot be detected, and couldn't even be added to the config.xml. I'd propose a two step approach: - have the config files listed in config.xml - add an optional opkg API function which lists the files to back up (this one is opkgs specific and could parse the config files to detect what ohter files they are refering to). It remains a non-trivial problem, I think, and requires some knowledge about the applications and OSCAR (from the administrator) to do it right...
