I would recommend not to waste time on rollbacks, because a package based
rollback will only work when a package's installation is non-stateful. This
applies to many "trivial packages", but does not apply in general.
Rollbacks works the same like downgrading?, Is the same task?
Downgrading is important when, for example you need to use xorg 1.17
instead of xorg 1.18 in order to install a nvidia privative driver
because nvidia does not works with the new xorg version.
