Building Rasplex ?

 I'd like to make some big changes to my local version; things like disable password auth in sshd_config and maybe some python packages to write out to a small LCD panel to let me know what's playing etc. (using https://github.com/adafruit/Adafruit_Python_SSD1306).

 

 I've checked out the main repo, but some things are .. unclear.

 

 What is a 'CI' build ? 

 How do you run a 'make menuconfig' on the kernel (I'd like i2c and some other things).

 How do you choose an RPi vs. RPi2 image build ?
