DNF5 will provide a setting to not load file list, as well to not create disk cache, or not using zchunk (already implemented in DNF). How it can help? It allows to trade download for disk space and CPU, or RAM for HDD, or RAM, HDD, CPU for features. And each user prefers or requires different different things. > > Without file lists there will be not available some functionality: > 1 dnf install/repoquery/whatprovides <file outside of /etc and /usr/(s)bin> => will not work > 2. resolve transaction can fail - keep in mind that people are not only using packages from Fedora distribution. Hmm, when this was discussed previously, the idea was that DNF would not load the extra metadata initially, but when in encounters a requirement for it, i.e. something refers to the paths outside of core list, it'd load the extra metadata, possibly downloading it, and restart the transaction. Having this predetermined by a config option doesn't sound nearly as nice… Zbyszek > For some users such a change can be a problem, for others not and they will see benefits. DNF must provide a solution for all of them and DNF5 will but there is only one default setting therefore some users will need to modify dnf5 configuration to achieve what they need. _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
