Linux on a plane

The entertainment system on my recent United flight had to be rebooted a couple of times (in fact they had to reboot it 5 times). It was interesting to see that the system was based on the Linux. Panasonic Avionics the maker of the entertainment system had the 'original' boot screen you see on Linux systems. It provided me with all the details of the disk partitions, memory maps, CPUs etc. I presume the engineers at Panasonic Avionics decided to keep the boot sequence untouched but for the computer unsavvy travelers this display on a plane might be very intimidating. I didn't have my Nikon on me so had to take a picture using my iPhone. I have posted it on here. I was just glad to see Linux being utilized in Avionics.
