The linuxMCE team has done a great job with the installation. While not on the level of something like the LinuxCNC distro, which is ready to go (for the most part) after the initial install, its still fairly straight forward, requiring a few more steps to get the system functional. The one thing the install is not is fast. It takes some patience. I had my own issues when trying to learn/install the system for the first time. Many trips to many websites, kind of a nightmare. What I learned from all the sites about the install is here, in one place.
With version 810, linuxMCE is installed as a hybrid/core. That is to say, the installation installs all the Core software, and Media Director as well. As far as I can tell, there is no way to change this during installation, you must simply do the install, then edit /etc/pluto.conf file, setting AutostartMedia=0. The default runlevel is 5, which also includes KDE. You can edit /etc/inittab to change the default runlevel to fit your needs. I chose runlevel 3 - textmode console, as my Core machine will be headless.
Adding an options screen during installation would be a simple addition. It would save many questions, and speed the installation if your running a Core only machine.
