IIRC, there is now a thing called "FreeBSIE" which is similar; a CD live
filesystem OS on a bootable CD that's basically a "FreeBSD Demo."
Never tried it myself.

I think FBSD has had "Picobsd" for years, which operates very similar
to what you describe. Make a CD or even floppy, set it r/o, boot your
firewall boxen from it ...
$man picobsd
