No, it is a few months old now with lots of reboots.  It is my experiment to 
build a reliable PBX out of Seagate Dockstar hardware and USB sticks. I've now 
blown up about three 4G sticks, presumably for heat issues (?), and have just 
bought an "SLC" based stick (which was not easy to find) that supposedly has a 
better heat range and longer write life.

Once I got it working I saved a dd image of the stick and have just been 
imaging the new sticks as I try them.  This *is* the first boot on this new 
stick, but the filesystem itself is "old", with several reboots.

I don't really care about the uptime calculation, just thought it was funny. 
It is strange that asterisk and the OS don't agree... so how does asterisk 
compute it?

FWIW it makes a fantastic home PBX.  I use it daily to make conference calls 
that last for hours, and other extensions in the house make and receive calls 
at the same time.  It has *just* enough RAM to not swap, and I have turned off 
all the logging, so there aren't that many writes to the USB stick.  Pretty 
fantastic for about $40 in hardware.
