I've been using packaged base for quite some time, cross-building on FreeBSD/amd64. Every time I upgrade FreeBSD via "pkg upgrade" it seems to me that it does not take an inordinately long time. It takes longer than packaged base on a regular FreeBSD/amd64 server with spinning disk, but not an excessive amount of time.

I am using already existing documentation from the FreeBSD project. (Many thanks to the original authors!) 1. Building and serving pkg packages For a long time I have built packages for my FreeBSD systems using Poudriere and serve them over the network via the Poudriere build machine. See: - https://www.freebsd.org/doc/handbook/ports-poudriere.html I use Nginx (via www/nginx) to serve the pkg repos (based on the /usr/local/share/examples/poudriere/nginx.conf.sample file in the ports-mgmt/poudriere installed port). Note, you don't really need Poudriere in all this, but I find it useful for also cross-building my FreeBSD/arm64 ports. Because I was using Poudriere long before PkgBase, I included it here as something folks might also want to use. 2. Cross-building for FreeBSD/arm64 To cross-build, I use the "mk" script provided at the arm/crossbuild section of the FreeBSD Wiki. See: - https://wiki.freebsd.org/arm/crossbuild In the case of my FreeBSD/arm64 systems, my "config/mk.conf" and "config/make.conf" consist solely of the following: ===== config/mk.conf ===== mk_arch="aarch64" mk_kernel="GENERIC" ===== config/mk.conf ===== ===== config/make.conf ===== REPODIR=/build/repo ===== config/make.conf ===== I have a simple script, "rebuild_os_pkgs" that cross-builds everything and makes the base packages that end up under /build/repo: ===== rebuild_os_pkgs ===== #!/bin/sh mk buildworld mk buildkernel mk packages ===== rebuild_os_pkgs ===== (My "mk" script is in /usr/local/bin.) To build an updated OS I run that script after first having updated the OS source in the "src" subdirectory (e.g., via "make update"). (You can symlink "src" to "/usr/src" if you want to save space.) The "mk packages" step results in a pkg-compliant repository with all the PkgBase packages in it. 3. FreeBSD/arm64 PkgBase I followed the PkgBase documentation at the FreeBSD Wiki to set up my Raspberry Pi 3 to use the OS packages build on the FreeBSD/amd64 build machine using the "rebuild_os_pkgs" script. See: - https://wiki.freebsd.org/PkgBase I have this snippet on the OS package build machine to serve out the pkg repository created as part of the rebuild_os_pkgs run: ===== location /FreeBSD-base { alias /build/repo; autoindex on; allow all; } ===== If you are used to building and serving pkg packages (e.g., ports packages) then the real workhorse in all this is the "mk" cross-building script + FreeBSD build system that is cross-building capable. I encourage folks to check out the FreeBSD documentation on cross-building for ARM and PkgBase that I mention above. They have a lot of useful information. Cheers, Paul.help
