Allows one to build a Raspberry Pi-based BMC unit for an IPMI-less server. The Raspbian system must include the package screen and (via pip) the Python libraries python-daemon and raspberry-gpio-python (installed by default).

More information can be found here: https://www.boniface.me/post/a-raspberry-pi-bmc/

There are three main files:

bmcd - BMC Daemon

Runs in the background of the system and handles reading and writing GPIO.
bmc.sh - The BMC shell

Should be set as the default shell of the login user (bmc) and provides user interface to the BMC.
rc.local - The rc.local file

The system rc.local should be replaced (or symlinked) to this file to start the bmcd daemon and screen console session on boot.
