Not that I'm familiar with the details, but I'll note
nanobsd as a possible source of some ideas for builds
and installs for embedded applications, not necessarily
tied to the specifics above:

https://man.freebsd.org/cgi/man.cgi?nanobsd

Some quotes:

"nanobsd.sh  --  utility used to create a FreeBSD system image suitable for embedded applications"
. . . .
"The mass storage medium is divided into three parts by  default (which are normally mounted read-only)"
. . .
"The /etc and /var directories are md(4) (malloc backed) disks".


I've no clue if it would be an actual help but it sounded
like it might have potential. If not, sorry for the noise.
