If you are like me, you’ve typed “make buildworld && make buildkernel && make installkernel …” about a zillion times. Now, you can encapsulate that process in a shorter statement: ‘make build-all install-all‘. The real benefit is these new steps also run in parallel to match the number of CPUs present, and logs to file instead of the console, automatically.
It’s been forever and a day, but i seem to recall that in the beginning ‘make world’ was all you needed.
Pre-DragonFly, you mean?
Early FreeBSD for sure, tho i have a vague recollection of it being the case in DragonFly as well.
