They clearly haven't looked very far for use cases, indeed.
Another important use case (and another reason why keepcache=1 should not
only be supported, but IMHO even be the DEFAULT):
* Say an update to NetworkManager or one of its dependencies breaks your
networking. (Maybe it's an unusual configuration that was missed during
* Even ignoring the issue of mirrors not keeping old updates (which I
already pointed out earlier in this thread), with networking not working,
you simply CANNOT go to a mirror, directly to Koji etc. to get a
downgrade. The ONLY place to get the old package from is your yum cache.
* If this is not the first update to the package, you will definitely have
the previous (or at least another recent) update cached.
* If this IS the first update to the package, if (like me) you used the
direct yum method to upgrade Fedora (and of course keepcache=1), you have
the GA package cached. I don't know how FedUp handles this, but if it
doesn't keep the cache, it should!
In that situation, with keepcache=0, the installation is BRICKED! With
keepcache=1, it can be fixed by downgrading the offending package from the
cache (rpm -Uvh --oldpackage).
