Features/LimitScriptletUsage

Beta
Work in progress

Limit Scriptlet Usage of core packages

Summary

Remove direct scriptlet calls from "core packages" (those that are used to build minimal container image). The packages can still affect changes during installation by placing files in the correct locations to trigger registered external programs.

Detailed Description

Remove direct scriptlets from most (if not all) of the packages in the main fedora container image. This means all four of: %pre/%post/%preun/%postun. After this change some kind of temporary exception would have to be granted before those packages could add a scriptlet back.

Benefit to Fedora

At the moment all of the packages with scriptlets (and anything installed with them) are basically opaque programs that happen to also carry files that are installed, from all of the packaging tools (rpm, ostree, composer, etc.) . After this change the entire installation of the main container image will be declarative, and thus. understandable by all of those tools. This should make things faster, and allow new optimizations (as well as features).
