Hi, Over the weekend I've been looking at writing a Yum plugin to support functionality which I've called "repogroups". What I want to do is to organise my repos into groups and then arrange for packages to be preferentially updated by those in the same group. I also want to be able to use these groups to specify preferred repository groups for installing new packages. A possible use-case I have in mind: - core packages come from a stable distro (with a core and updates repo). Packages from the core are updated from these repos where possible, and new packages are installed from these repos where possible. - selected packages are taken from a more cutting-edge distro (also with core and updates repo). Packages from this distro should be updated with packages from these repos where possible. New packages are installed from this repo where either not available in the above, or where a command-line switch changes the preferred repogroup order. - other packages may come from other repos which are not in a group (the null group, if you like). these have the lowest priority. upgrades come from these repos only for packages originally installed from a non-group'd repo, and installs from these repos only if none of the groups can support the request. Firstly - is there already a sensible way to do this and/or existing code that does so? Assuming not, is there a sensible way to achieve this? Ideally I want to be able to vet the list of candidates for satisfying a given name/dependency and choose the one that meets the requirements best. I looked at protectbase's use of exclude_hooks, but these are a bit draconian as it's possible it may exclude packages needed to satisfy a dependency unnecessarily. I also looked at using a postreposetup_hook but that requires basically taking output and redoing the dependency resolution again. It's particularly icky because as far as I can see there's no way for this hook to know what the original reason(s) for including the items in the transaction set are (ie. what dependecy resulted in this member being added?) Any thoughts? Thanks, an apologies for my vagueness. Luke
