Bug #477752: resolvconf: Don’t reinstall init script on upgrades

Probablement à cause de la politique appliquée aux paquets ayants des bugs non corrigés dans le délai imparti.
[quote]Removals from testing
There have recently been some raised eyebrows about removals from
testing. The release team has a clear policy in the matter: packages with RC
bugs older than 20 days, with no activity from the maintainer are reason
enough for a removal from testing. Only packages that are leaf nodes in the
dependency tree get removed this way.
This does not mean (yet) that your package will not be shipped with lenny, a
new upload with the offending bugs fixed, and the package will transition like
any other.[/quote]
Comme le bug en question a été corrigé il y a quelques jours, le paquet devrait être réintégré dans lenny bientôt.
