Yes, you are right. The reason I added it was is that because on my centos 5 x86-64 machine to be I was not able to run vzpkg correctly, it failed because it tried calling a script which is part of vzctl-lib. As you say there should be a dependency in place, but I experienced . My experience is that it is missing. Therefore I recommend to add vzctl-lib to the yum-command. It will not cause any problems if the dependency is in place, right?
