Don’t have much time due to work obligations but I wanted to quickly drop this one out there for any who have followed my install guides. I was always ragging on and on about making the install somewhat portable by putting it into the /opt/ directory and now I’ll give a good example why.

Ubuntu loads a ton of them and many I do not use at all. Since when do you need joystick or sound support on a server anyway? Anyways, here are some I disable and how I disable them.
