[opensuse-buildservice] Package groups
Hi, currently I need to simplify the installation of about 100 packages with many inter-dependencies. As rpm and rpm-based installers sometimes install in a very disadvantageous order and I was unable to cover that via package requirements*), I created meta packages which are to be installed in a certain order to setup the software. A disadvantage is that I cannot uninstall all these packages easily that are installed by meta-packages. Now I saw that RHEL based systems have the option to make use of package groups which are defined in comps.xml files in the repository metadata [1] and I know that SuSE based systems allow to use patterns (and both are my target platforms) I would like to read a comparison between meta packages, package groups, patterns and distribution compatibility and if/how it is possible to create package groups/patterns with OBS. Does someone have more information about that topic or can show me examples on build.opensuse? It seems I am googling the wrong questions :-) Best regards, Mark [1] https://fedoraproject.org/wiki/How_to_use_and_edit_comps.xml_for_package_gro... *) Example: Some packages have an absolute requirement that another package was installed completely before, including all pre, post and other phases; if zypper/yum/rpm install the packages together, anything could happen - e.g. alphabetical order or whatever; a simple Requires does not help and Requires(pre) does not help either. -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org

seems you want to cover deployment work already by installing the rpm packages? Maybe this is the wrong effort to solve your problem. Packages should be installed with an universal (example) configuration and configuration should than be done by a configuration management system (ansible, puppet, salt, ...). All of them can install your packages in a defined order on rhel- and susebased systems (and others of course too). Sorry for not answering your original question, but maybe it helps you anyways.
