## Explanation
Attempting to kickstart CentOS 6 works correctly. Attempting to include post-DVD updates during kickstart causes lots of scriptlet failures. Can someone tell me why this happens?

Specifically, I know why the failures happen (look at the order of package installation between the two outputs). I also know why rpm doesn't get the transaction order right (the scriplets are missing appropriate requires entries). What I don't understand is why pulling in update packages triggers this issue or why a regular install seems to always work.

I believe there are couple of bugs involved here:
 - the sudo package does not contain a Requires(post): /bin/chmod
 - the anaconda transaction order solver doesn't take scriplet requires ordering considerations into account beyond one dependency level (so the Requires(pre): /usr/sbin/useradd requirement is fulfilled by the time openssh is installed but anaconda doesn't extend that to ensuring that regular Requires: entries for shadow-utils are ordered correctly)
 - that for some r
