Basically, I was thinking about package dependencies, because it's very easy to break script-based applications by corrupting the interpreter underneath, than it is to break a binary application. Problems like this http://www.redhat.com/archives/fedora-devel-list/2004-November/msg01218.html are typical for script-based applications. A subset of such problems are rpm-dependencies, which are very easy to miss with python. E.g. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=140140 is such kind of bug. Even the infamous "system-config-security-gui"-bug https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=139155 partially originates from this fundamental issue (Somebody changed the interface of one tool and forgot to reflect these changes in the python- GUI). There's no guarantee such kind of bug won't occur with binary programs, however the likelihood for them to happen is (IMO significantly) smaller. > Or are you thinking about > "deficiencies of poorly-written programs in general". No, that's not what I was referring to. Although, ... scripts in general tend to be much slower than binary programs, and resolving graphs (rpm-dependencies) in a scripted language also isn't necessary a design decision promising speed ;) Ralf
