[Rpm-maint] Package replace implementation

[Michael Schroeder]

Hi,

seeing the latest "replacepkgs" commits (030e54), I wonder if we
should not drop that crazy refresh handling and simply use an
uninstall element to erase the package.

Currently, rpm works different if the EVR of the to-be-installed
package matches the installed package:

foo-1-2 -> foo-1.3   (upgrade)
  - run prein/postin of foo-1.3
  - run preun/postun of foo-1.2

foo-1-2 -> foo-1.1   (downgrade)
  - run prein/postin of foo-1.1
  - run preun/postun of foo-1.2

foo->1.2 -> foo-1.2  (replace)
  - run prein/postin of foo-1.2
  - does *not* run uninstall scriptlets or deinstall files no
    longer in foo-1.2

Why doesn't it run the uninstall scriptlets? What makes "same EVR"
so special when the package content may be different nevertheless?

Cheers,
  Michael.
