I am not aware of a way to do "or", but as long as the packages provide a shared provides then a end user can manually ensure their preferred package is installed, leaving you to not care. I'm not sure how an automatic dependancy resolution would end up. For this specific the OpenJDK package provides 'jre' just like the Sun/Oracle package, and apparently the IBM one as well. So I would just require the item you deem most appropriate, and thus you just provide one package. $ rpm -q --provides java-1.6.0-openjdk | egrep '(java|jre)' config(java-1.6.0-openjdk) = 1:1.6.0.0-1.11.b16.el5 java = 1:1.6.0 java-1.6.0 = 1:1.6.0.0-1.11.b16.el5 java-1.7.0-icedtea = 0:1.7.0.0-0.999 java-fonts = 1:1.6.0.0 java-openjdk = 1:1.6.0.0-1.11.b16.el5 java-sasl = 1:1.6.0.0 jre = 1.6.0 jre-1.6.0 = 1:1.6.0.0-1.11.b16.el5 jre-1.6.0-openjdk = 1:1.6.0.0-1.11.b16.el5 jre-openjdk = 1:1.6.0.0-1.11.b16.el5 libjava.so()(64bit) libjava.so(SUNWprivate_1.1)(64bit) libjava_crw_demo.so()(64bit) libjava_crw_demo.so(SUNWprivate_1.1)(64bit) java-1.6.0-openjdk = 1:1.6.0.0-1.11.b16.el5 $ rpm -q --provides java-1.6.0-sun | egrep '(java|jre)' jre-1.6.0-sun = 1:1.6.0.20-1jpp.1.el5 jre-sun = 1:1.6.0.20-1jpp.1.el5 jre-1.6.0 = 1:1.6.0.20-1jpp.1.el5 java-1.6.0 = 1:1.6.0.20-1jpp.1.el5 jre = 1:1.6.0 java-sun = 1:1.6.0.20-1jpp.1.el5 java = 1:1.6.0 javaws = 1:1.6.0 java-sasl = 1:1.6.0.20 libjava_crw_demo.so()(64bit) libjava_crw_demo.so(SUNWprivate_1.1)(64bit) libjava.so()(64bit) libjava.so(SUNWprivate_1.1)(64bit) java-1.6.0-sun = 1:1.6.0.20-1jpp.1.el5 $ rpm -q --provides java-1.6.0-ibm jre-1.6.0-ibm = 1:1.6.0.7-1jpp.2.el5 jre-ibm = 1:1.6.0.7-1jpp.2.el5 jre-1.6.0 java-1.6.0 jre = 1:1.6.0 java-ibm = 1:1.6.0.7-1jpp.2.el5 java = 1:1.6.0 javaws = 1.6.0 java-sasl = 1:1.6.0.7 libjava_crw_demo.so()(64bit) libjava_crw_demo.so(SUNWprivate_1.1)(64bit) libjava.so()(64bit) libjava.so(SUNWprivate_1.1)(64bit) java-1.6.0-ibm = 1:1.6.0.7-1jpp.2.el5 Based on looking at that, I would assume that by using the epoch, Sun would win in the dependency game regarding jre, and still not sure how the dependency on java would play out. -greg _______________________________________________ Rpm-list mailing list Rpm-list@xxxxxxxxxxxxx http://lists.rpm.org/mailman/listinfo/rpm-list
