What, if any, indicators of system status or activity are available on the R-Pi?
Audio - I'm talking about a beep when it's turned off, or a series of beeps indicating POST information etc
Video - Does it have a power on LED, what about a disk activity LED etc like you get on the front panel of a lot of PCs etc.
If none, are there any peripheral options available to connect via USB in order to present such information?
I am considering a headless project for use in-car (continuous loop recording of audio, parking sensors etc) and would like to know that it's working without having to login etc.
