Let's be honest: OpenVPN it's a pain in the ass to install if you need a quick VPN running. I didn't wanted to lose 15 minutes each time I needed it on a server, so I did an installation script.
I know there are other scripts available, but they seem rushed, very intrusive and never included any form of uninstaller.
So here we go: I written a clean script, that isn't intrusive and works on Debian-based systems. I will keep it updated as needed and if someone wants to port it for other distributions, it's free to do so!
