From: "Felipe F. Tonello" <eu@felipetonello.com>

Since when updating packages packages managers do not remove the previous package,
it just replaces new files and run pre/post install scripts. This causes not
to update update-rc scripts if they were changed.

This patch is useful in case the newer package version updated the update-rc
script.
