Nard for embedded music installation

[Daniel McAnulty]

Very cool clock radio!  That's a great idea and implementation.  

I've been trying to find if there's any good research on successive power 
cycling with Nard vs a standard Read-Only implementation of Rasbian?  

I'm thinking for this project I'll probably set up a power supply on a timer
to power cycle the device a couple hundred times and make sure it's still 
working at the end of it, but I would imagine I'm not the first one to 
want to do that.  Has anybody else published research on it that anyone
is aware of here?  I've looked but haven't found anything reliable.  

Hahahah, I just got to the part of the RSS channel feed where the Raspberry
Pi is reading off the news about 'the New South Wales forest where a 
notorious serial killer buried his victims', it's a little jarring :)

Super cool though, that looks like a fun way to wake up.
