Off topic question: what's the current process to make extremely small "minimal" freebsd server install? Is it NanoBSD[1], because the unfortunate downside is that the base can't change (I realize that's a feature) and for a web server or database server that might not be ideal.

This may not be the answer you are looking for, but OccamBSD seems to be a way to produce a minimal image for use in FreeBSD jails, FreeBSD bhyve and Xen: https://github.com/michaeldexter/occambsd https://github.com/michaeldexter/occambsd

If you're building from source, then I'd just disable what you don't need via src.conf(5)'s various WITHOUT_FOO settings. They are described in the man page itself.

I did this a while ago. the .iso.xz came in at 22.1 MB and the .iso at ~80MB. That's for a ro image with tmpmfs and varmfs[0], a minimal kernel, base and the packages nginx-lite, jansson, re2, curl, acme.sh and some services. The system boots from an ISO into running nginx and hosting a basic network scanner[1] at a VPS provider. I basically built from source with a custom SRCCONF[2], KERNCONF[3] and some other cleanup[4]. There may be easier ways to do it but it worked out pretty well for me.

You may be asking for something different, but FreeBSD Jails can be extremely small, even down to just a single process[0][1].
