I believe you would need to do one more rebuild+reinstall without your changes to begin using freebsd-update. Otherwise, https://docs.freebsd.org/en/articles/freebsd-update-server/ describes self hosting it and the warning at the top implies efforts will need to go to pkgbase in the future. Vermaden attempted it and ran into issues which went unanswered for a while so switched to doing the same but with pkgbase and had success. Vermaden has posts about most everything in this topic if I recall. > 2.

Now I'd add that reboot from step 3. Step 6 should be done 'after' packages have been upgraded; add relevant `pkg upgrade` effort here first. Restart programs/services as needed or reboot computer. > 6) make check-old-libs delete-old-libs Again the check-... isn't necessary and -DBATCH_DELETE_OLD_FILES will help by answering yes. > But this gets quite cumbersome with many different FreeBSD VMs. I'm > looking for an upgrade process similar to how NetBSD does it. > > Specifically: > > 1) Build release.

I'm not familiar with etcupdate steps for use on tgz file data; it is a 3-way diff used to compare configuration changes between an original state, your modifications, and an upgraded state so I presume a workflow could be done. I don't know pkgbase workflow yet but seems 'in development' for documents I find despite some people being regular users and testers of it. The most minimal steps seem to involve an install not being modified much when converting to pkgbase, even going so far as to convert to it before completing configuration steps in the installer and performing those after. The more that has changed, the more has to be reviewed and the initial migration steps haven't sounded nearly as nice as the usual etcupdate workflow. etcupdate already knows what you have changed; it can be helpful to note/save those details for consideration when migrating to pkgbase. If using pkgbase, it is recommended to keep backups of your configuration. > Can something similar be achieved with FreeBSD?

The fastest+simplest way will likely become pkgbase to perform those steps assuming etc migration is well managed. https://wiki.freebsd.org/PkgBase has some good information but I don't know how up to date it is (wiki is usually not up to date when I need it for topics). https://lists.freebsd.org/subscription/freebsd-pkgbase is also likely good to follow. If every system is not a different version or built with its own custom options then I see 3 possibilities: 1. Run it once and share the build directory skipping to step "2)" for each machine. This sounds like it maintains your current workflow with the least amount of changes 2. Share a self hosted pkgbase repo among the machines if you require 'some' customization from what you can find on pkgbase repos for RELEASE, STABLE, and CURRENT builds. Again, I'm not familiar with configuration update steps as pkgbase is a newer system. I do not know if old libs are kept around or software requires an update at that time to function properly; since the primary goal is `pkg` updates base and other packages with the same tool (though not yet at the same time) I presume keeping old libraries is deemed unnecessary or is likely a pkgbase bug. 3. Share resulting tgz installer packages that you built. `man release` to learn to begin such build steps. Cleaning out old files and merging changes is not part of the toolset as these are used for new+fresh installations by the installer and no notes are created about what was installed or where; this is why this would be the least desirable and trying to create fixes for this scenario is what leads to pkgbase as an effort. I believe it is planned to have the installer use pkgbase from the start of a system being installed. A workaround to do it cleanly would be using boot environments to make clean partition(s)/dataset(s) to extract them to and copy/edit your configuration into the new system. Though not part of your original question, if you have to build your own system due to desired changes to how base and/or kernel are built, then if you haven't already you can speed up the build using ccache or ccache4 and additional speedup setting up WITH_META_MODE (`man src-env.conf` for more details). If any of the VMs are on separate hardware, you may get additional performance using distcc depending on the hardware of each and networking performance. These are all set-and-forget steps other than periodically manually cleaning up ccache repo if used on ZFS. > Thanks. >
