Oh, I have no doubt.
Every component is there because it's needed for something.
comp${VERSION}.tgz is needed for compiling e.g. the system itself,
man${VERSION}.tgz for looking up the latter process...
But, as my experiment showed, a MP system consisting only of
bsd.mp and base${VERSION}.tgz boots and operates perfectly.
Hence, /bsd.sp is (maybe needed as fallback
in case of a MP bug, but) not *absolutely necessary*.

But ok, I guess I'll have to answer the "Are you *SURE*"
question via /auto_upgrade.conf before rebooting...
