I've recently been going through our environment here at work and getting the McAfee modules installed on our UNIX environment, which took a lot of Googling to figure out the commands and what not to get everything working properly. As a disclaimer, McAfee 5.0 really helps out with adding a lot of functionality for non-windows systems that MA 4.X was lacking. But nevertheless, a lot of machines just wouldn't install, and it takes a good amount of manual process to get everything working properly. We only have linux/solaris, so this is only pertaining to those operating systems.
Anyways, just thought I would post them up, they are attached.
