Didn't have anything better to do ... here's a "trivial rpm" implementation which allows simultaneous install/upgrade/erase from the command line but nothing else: http://laiskiainen.org/rpm/examples/ , eg # ./minirpm -e telnet -U foo-1.2-2.i386.rpm -i kernel-2.6-1.i686.rpm Feel free to include to rpm's examples, fix if you notice silly errors or whatever. Should build + work on any rpm >= 4.1 systems. - Panu - _______________________________________________ Rpm-list mailing list Rpm-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/rpm-list
