Please, if possible add yum transactions history "yum history", "yum history undo", etc. support into zif (and maybe in PackageKit).
We've got yumdb support : http://people.freedesktop.org/~hughsient/zif/howto-pk.htm I'm not sure how the yum history undo function works. What do you use it for? Does it always do what you expect?
yum history uses other databases than yumdb located in /var/lib/yum/history/ Description available here: http://yum.baseurl.org/wiki/YumHistory
I am expecting from this command showing history of transactions and possibility to undo any of them.
