I was wondering why the build creates a libkern.o (so all the objects
are included in every kernel) rather than a libkern.a so that only the
referenced items are included?

My suspicions have to do with ensuring that LKMs have all the functions
available...

OTOH the install kernel will fit if built with a libkern.a ...
Although cutting down on sysctl would also help.

I also have half a plan to police the size of the small kernels, using
a script that will report the guilty party when it all stops fitting.
