I only stumbled on them by doing
sysctl -a | grep fib
It's often surprising what you find that way.

In the source the exec.fib parameter is given as an integer, so the
quotes probably shouldn't be there, but I'm not sure whether it matters.
There's definitely a setfib call in the source that's done if exec.fib
exists. All I can think of right now is that you try firing up the jail
using the -v verbose flag. This should show everything the jail command
does as the jail is created.
