Linux on Delta

I ran into the exact same screen during my Delta flight to LAX last week.  The reboot occurred for me when the power seemed to blip for a second.  I too was surprised that there was no customized boothsplash.  From what I could tell during boot it's a 5-6 year old Red Hat variant that was doing a PXE-like boot and then remote mounting /usr/apps2 before going into a custom GUI.  It still amazes me where and how consistently you see Linux pop up these days.  I admit I was hoping it would reboot again so I could get more details, but no such luck.
