Not have a 1 liner installation script that's a security nightmare? :)
eg, this is the Countly one (specifically run as root):
wget -qO- http://c.ly/install | bash
If someone manages to break into the c.ly redirection service, or the website/CDN/etc serving that, new users would likely be in for a bad time. And the problem could be very subtle, if it's done by someone clueful.
Just for added er.. goodness (/s), the Countly instructions also need people to:
Disable SELinux on Red Hat or CentOS if it's enabled.
Countly may not work on a server where SELinux is enabled.
In order to disable SELinux, run "setenforce 0".
