But my hypothetical CD-R kernels all print "Say farewell to Nova
Scotia" on the screen just before entering user space for the first
time.  Or maybe it's only the kernels I boot on Mondays which use
that particular message.

Of course, *any* trust placed in a computing device other people
have control over is risky (much fun could be had by storing away
compressed snapshots of video memory every 5 minutes...all you
need is a way to convince my kernel to call into the BIOS
periodically...hmmm...how about that APM entry point?).

You always need to draw a line somewhere.
