If from the very start, after installing from a live media install if you set it true, maybe at the end of a Fedora cycle you may end with some gigas stored in your /var/cache/dnf, I still conserve my fedora 17 cache and is about 4 GB even when I reinstalled it because of unconformity with Fedora 18. So the unique limit you have is delimited by the space you have to store data on your /var/cache/dnf, many people recommends having /var/ in a dedicated partition, even on a dedicated disk. The are not limit on the size apart from the size of the disk/partition, there are not limit on the number of packages nor it's numbers of versions. >> Even if it is set to False and packages have not been installed they will >> still persist until next successful transaction.
