We do this via a custom build and creating packages as this is introduced at https://wiki.freebsd.org/PkgBase But beware! As many others have already stated, take care about to use the least common denominator of achitectural specifications amongst your pools! This means to not use any kind of optimizations for a specific CPU type for pkg-base distributed builds! Because we build the local OS for fast/server machines always(!) with optimisations, the pkg-base builds are done in a separate way - which is very easy if you've once understood the really neat and great build framework of FreeBSD's! Instead of building the traditional (probably optimised) system from /usr/src and /usr/obj, now you've to consider a separate path like /pool/sources/CURRENT/src (our way, since we also try to build packages and object trees for 11.X), then setup a small build script that essentially sets MAKEOBJDIRPREFIX KERNCONFDIR KERNCONF and especially __MAKE_CONF SRCCONF SRC_ENV_CONF if you use usually optimisations for the native target build on the building host and more generic binaries for the Intel x86 crap for redistribution. Doing so, we also perform builds for some ARM64 based experimental boxes. The next step is then up to you how to distribute. We copy all the pkg stuff coming out of the build cycle to a folder which is accessible by pkg via HTTP(S) - so www/apache24 is our platform to redistribute the binaries over the network and even to remote sites (beware of the security implications!). You also can distribute the obj-folder (/usr/obj, or, if using another approach, like /pool/sources/CURRENT/obj) via NFS. Once you've understood the (easy to learn) concept of building the source tree, creating the packages for pkg-base and having dealt with the more labor for the setting of a distribution server, you can use the most potent server/box on you network for building dedicated distributions Even a "Release" build is possible as long as there are not pitfalls like they occured during the transition from 11.X to more 12-CURRENT spcific development (i.e. LINT). If you use pkg-base as mentioned above, be aware to setup a proper pkg.conf file as introduced on the Wiki and please be also aware of the fact, that there is at the moment no sharp separation between pkg-base and oridnary pkg for packages - so take the warinig serious, that pkg delete -a will not only kill all packages, it also will kill all packages installed for the base system! Once installed you'll see how fast compared to source build the pkg-base installation is (although I still prefer source build, optimised builds ...). And by the way: depending on the sophistication of your build script for dedicated tree builds as mentioned, via manipulations of __MAKE_CONF, SRCCONF you're able to also build optimised binary trees for different CPU types, but you have to deal yourself with the fact that you've to put the binaries into a proper place and then delegate the URI in pkg.conf to the correct branch of your tree. The ABI environmental variable doesn't take care of the "set" you may have used to optimise. But this is something you're able to deal with easily yourself after having setup your basic build environment. Regards, oh - -- O.
