Maybe, but when upgrading you should also unload the old LKRG module and
load the new one.

I think this works and isn't an awkward hack:
make uninstall
make install
In fact, ideally "make uninstall" would be run from the old version's
tree. That way, things would be cleaned up if e.g. we ever rename or
stop installing a file. OTOH, maybe we should enhance "make install" to
detect old version installs and clean those up as necessary.
