I have to +1 very loudly for Arch. It has an absolute dream of a documentation. Any configuration or cache paths are default, the distro doesnt try to fuck with it like Ubuntu and others do - you do `man mytool` or look at the official docs for that tool, and if that says the config is at /etc/monkey/mytool.conf, it is.

The package manager works well.

The installer is very solid by now.

It comes with absolutely nothing preinstalled, perfect for techie people.
