As its name suggests, "make buildworld" doesn't actually install anything on the current running system. It builds a version of the OS under MAKEOBJDIRPREFIX (/usr/obj by default). To actually install what's built, you ultimately need to use something like "make installworld" to update the current system. > Well given that I am trying to build everything then it isn't a problem. > > The problem is the docs are ... not very helpful. > > People have suggested to me that make buildworld should NOT be followed by make kernel but make buildkernel : > > https://svnweb.freebsd.org/base/head/UPDATING?view=markup#l1770 > > The "handbook" is just plain wrong. I disagree. In the context where it uses "make kernel" in the Handbook, it's one where it's describing how to update a current system in-place. In that context, "make kernel" is okay, inasmuch as it's equivalent to "make buildkernel" followed by "make installkernel", which is what the /usr/src/UPDATING snippet you reference above is doing. Further down in the Handbook page, when it describes building a kernel, it actually uses "make buildkernel". Similarly, when talking about installation, it uses "make installkernel". Where the Handbook is lacking (in Section 23.5) is in its omission of the use of "mergemaster -p" or "etcupdate -p" prior to "make installworld", to ensure necessary new users and groups are present. I have used the instructions given in /usr/src/UPDATING for years as my canonical guide to building and updating the system. They have not failed me yet. The build(7) man page is also a good source of what the various build targets and settings are, as is the src.conf(5) man page---I've found the WITH_META_MODE option in /etc/src-env.conf is a good way of speeding up incremental builds.
