I suppose my point was that a dependency change, a single line in a text file, meta-information, shouldn't require the installation of the whole package.

I understand what is happening, even why it's happening from a technical perspective. What I fail to understand from a "this is just wrong" perspective that it's technically the way it is - which is why I posted to the list. I didn't want to get into the "incremental packages" discussion, but I thought that this was different enough to warrant at least some conversation about the meta-information associated with a package. I realise at present the meta information is also part of the .deb files but apt doesn't know about .deb's, so I presume it's getting the information from the pkgcache.bin file which I suspect is directly built from getting the package lists from a mirror. What I'm saying is that the dependencies are in that information, so there doesn't appear to be a need to download the .deb to install it if nothing inside the .deb actually needs changing. -- Onno Benschop Connected via Bigpond NextG at S31°54'06" - E115°50'39" (Yokine, WA) -- ()/)/)() ..ASCII for Onno.. |>>? ..EBCDIC for Onno.. --- -. -. --- ..Morse for Onno..
