IIRC, the original article (and this article as well) had some mention of rpm4 being highly distrospecific (lots of local patches). It's my *impression* (as an opensuse user) that this diversity has since been significantly reduced. Can anyone with more insight shed some light on this?
Another point mentioned in this article mentions that the migration from rpm4 to rpm5 isn't "simple" - scalability to a big distro and distro tools are mentioned. How much do these changes impact the "ordinary" package maintainer (required changes, bugs, other)?
