Barring any more specific suggestions, FreeBSD has a procfs(5) and, for
Linux compatibility, linprocfs(5). They both have kernel modules in
/boot/kernel which could be set up to load in /dev/rc.conf(maybe
compiled into kernel? I'm not knowledgeable about such things), and then
you can create and mount /proc or /compat/linux/proc respectively, using
the filesystem types of procfs or linprocfs, also respectively. That
might help get you what you need.
