Repo metadata is this stuff: https://blog.packagecloud.io/yum-repository-internals/My main concern was, if I use dnf to install a local rpm and afterwards I issue sudo dnf clean all to reclaim space (not that at the moment I have a need to be concerned about disk space) does that remove knowledge of the rpm having been installed? My assumption is no, given that the remote repositories packages are rpms anyway, but I didn't know whether remote rpms and local rpms are handled differently because of going through a different internal code path and hence having different restriction/requirements. Also in the past I have people on this mailing list query why I was using RPM rather than, at the time, YUM, and that I should be doing the installs through YUM.It's hosted remotely with the repositories, mirrored locally for speed when cache expires and is pretty much entirely throwaway, because you can (normally) always get a refreshed copy from the remote repository."knowledge of what packages have been updated" is open to interpretation. What's been updated/available *in the upstream repositories* is entirely in that "remote" repository metadata.What's been updated *on a local system,* is separate, distinct. I would guess that the source of truth here would be the rpmdb, maybe with a scattering of DNF data sources for speed, I've not looked into it in any detail.
