beat me to it by a minute or two :)

I'd guess (from a *nix-yness background) that the appliance is set up to
automatically fsck a disk if it's dirty - `dirtiness` can be caused by
thing like unexpected power cut as well as nasty things like hardware
troubles. Appliances are prone to "power pulls" as they are usually
headless. 
Some "diskless" appliances don't even bother to check , somewhat
dismayingly.

Not sure what the exact fs is on those boxes - anyone happen to know? -
but from experience, I wouldn't be worrying too much (though I'd be very
curious of course).
