Heads-up: RPM 4.8.0-beta1 about to hit rawhide

[Panu Matilainen]

Now that FESCo has approved new major RPM version for F-13 and the public 
beta is officially out... it's going to hit rawhide in a few hours.

Couple of practical issues:
- Soname bump is involved, so anything directly linking to librpm
   needs to be rebuilt. This includes deltarpm, gdb, net-snmp, abrt and
   a few others.
- The new version has integrated support for extracting OCaml
   dependencies, this clashes with the existing ocaml-dependency
   extraction mechanism in Fedora. Notably rpm-build conflicts with current
   ocaml-runtime, and the ocaml build-macros need updating to let the
   integrated pieces do their work.

And of course, watch out for regressions:

>From Fedora POV perhaps the biggest suspect is the python bindings as 
they've seen a pretty dramatic cleanup and revamp all over. It's supposed 
to be compatible for the commonly used parts (eg yum certainly works fine 
with it) but I'd be rather surprised if some rarely used dark corner 
hasn't broken up.

Another thing to watch out for is installation (and erasure) ordering. The 
algorithm has been pretty much rewritten and produces significantly 
different orderings than the previous one. However note that different != 
incorrect, the old algorithm completely blew it up in various dependency 
loop cases etc. So if something worked with the previous versions but no 
longer does with the new beta, it doesn't automatically mean it's a bug in 
the new ordering code: you might've just been lucky. Any regressions 
in this area need to be carefully analyzed case by case to determine 
whether they're true regressions or just incorrect dependencies in 
packages.
