Re: Occidentalis or Wheezy?
At least start with that, yeah. Once you have something that works, you can Frankenstein your way to a configuration that has everything you want, assuming the pieces will play together.
Keep a command/install log as you go. Ideally, your notes should be good enough for you to strip the machine back to bare metal and build a working configuration on demand. In practice, keep enough of a breadcrumb trail to avoid getting stuck in the, "okay, it does what I want, and I have no idea how to do it again" scenario. That sucks.
When you void a product warranty, you give up your right to sue the manufacturer if something goes wrong and accept full responsibility for whatever happens next. And then you truly own the product.
