Why does every distro need yet another package manager?
Some are improvements
People hang onto the one they designed
There are some formats with excellent features like segregation of build and use, consistency of product and signed manifests. BUT, if you don’t get why that’s important you’ll take a deb-based distro or one that builds continually in-situ and never realize it’s a risk.
Having said that, apt4rpm was great, yum was bad, dnf is featureless shit, and redhat is quickly broadcomming under IBM because #ibm. So go get PCLinuxOS and ask where the box templates are. And that’s my 25-year summary of package management.
