I am sorry if this is the wrong place but it seems that the rpm-list does not exist any more and this list looks to be the best fit otherwise. I am trying to create a few packages that all provide a virtual capability but would like to allow only one of these packages to be installed at a time. Has to be compatible with RPM 4.2 and greater. (RHEL4 and RHEL5) <snip> Name: package-a Provides: package-a config(package) </snip> <snip> Name: package-b Provides: package-b config(package) </snip> <snip> Name: package-c Provides: package-c config(package) </snip> I could obviously add Conflicts: package-b package-c to package package-a and so on, but every time I add a new package-X I have to manually go through my spec files and update the Conflicts tags. Again I suppose I could script the update but it seems less elegant. I tried: <snip> Name: package-a Provides: package-a config(package) Conflicts: config(package) </snip> But the result is: config(package) conflicts with package-a-1.1-1.svn20090428.noarch I thought I saw something like this in another list, will post link if I can find it. Where the goal was to only allow one package that provides a particular virtual capability. Anyone know how to accomplish this or if this is the wrong list can you direct me to a better resource?
