The major difficulty in "only updating packages that have changed" is identifying those packages. You can't compare the tarballs because there are all sorts of embedded timestamps in the tarball (and in files like lib*.a). I tried doing this once and it didn't actually provide much benefit for all the extra work it causes, because the majority of packages do change from build to build (e.g. because of updated dependencies, changes to the base system that change the generated code, etc). Of course, it's not fair to compare FreeBSD to an OS that almost never updates their packages (like Redhat). The only case you mentioned in your other mail that might compare is Debian. I'd need to have more information about their update strategy to make informed comment. I suspect it might come down to either not having the ability to rebuild their entire package tree more frequently (i.e. lack of build cluster resources), or a more conservative policy of how they choose to update packages.
