I recently ran a couple of dependency analysis on openSUSE RPM packages, and found it unintuitive that the RPM package dependency graph is not a DAG (Directed Acyclic Graph). Instead there are dependency cycles between them, for example:

``` $ rpm -q --requires terminfo-base | grep ncurses ncurses >= 6.5.20240713

$ rpm -q --requires libncurses6|grep terminfo terminfo-base ```

At least, it is not unexpected.

After all, these are run-time dependencies, not install-time dependencies.

Hmm ... to my best knowledge Requires in RPM defines install-time ordering. But there is no loop above - terminfo-base requires ncurses, not libncurses6.
