Check these sites out: http://www.linuxjournal.com/article/7034 http://lee.k12.nc.us/~joden/misc/patches/rpm/ The first one is an article in linux journal that pretty much documents rpm's transactional rollback feature and the second is the autorollback site which is an experimental feature allowing rpm to automatically rollback a failed transaction. Since you probably didn't use --repackage, you will need to re-install the old package using the --oldpackage option. That said, since your old package does not know what your new package did, this may or my not work. Another problem with rolling back scriptlets is presently, rpm does not allow your scriptlet to know if its being called in a rollback or a pure upgrade context. Typically, I use semaphores with upgrade and rollback scripts that wrap rpm.
