The only safe way to rebuild is with the full documented cycle that
includes a buildworld.  "Unsafe" means "may leave you with an unusable
system".  If you want to play around with other make targets you can
indeed short-cut the build process a lot of the time, but you're
expected to be advanced enough to recover your system on your own when
you damage something, and that pretty much means being able to figure
out how to use the make shortcuts on your own :-)
