In researching my question on mcrypt I realized that I don't know what I can and can't do manually with my system in regards to Virtualmin.
What should be avoided to prevent interfering with Virtualmin?
Can I use yum?
In other words I don't see a way to install mcrypt through Virtualmin.
If I install it through a shell using yum install php-mcrypt Will that create problems with Virtualmin?
Then for the bigger picture. When CentOS 5 updates to 5.2 is there a way for me to update to that through Virtualmin or will I need to do it in the shell? If I do it through the shell how will I know if that will be safe for Virtualmin?
Is there a list of everything Virtualmin manages?
Is there list of what it doesn't manage and how those things should be managed so as not to interfere with Virtualmin's functionality?
