Title: Fix #189: Don't call yum update

This addresses the issues raised in Issue #189.

`yum update` automatically upgrades all packages that can be updated, which is either annoying or catastrophic if it breaks running software. All Yum commands automatically refresh the cache before running, so this shouldn't be necessary.

Tested on Centos64 and found no issues.
