I am pretty sure that the weak-modules thing should just go. It's outdated cruft, for some enterprise thing, and inused in Fedora. I'd really recommend to just drop it from the Fedora package... > But, even if the size is small that is not the full picture.

That sounds wrong... Any idea how that gets pulled in? the dm libs might get pulled in indirectly via libcryptsetup, but the other dm tools really shouldn't be. And iptables i really don't see how that's pulled in? dbus (the daemon) is probably something we can turn around to not require. I mean, it's needed during runtime if you boot a full OS container or host, but I figure we don#t really have to pull this in like this...
