At work I have something like this, basically the setup have a small /
that is not encrypted, and I have a script called 'geli0' that starts
network, sshd and waits for the GELI provider be unlocked or someone
hit enter on console (and then unlock from console, of course).
I'm not sure if this is even near your requirement nor it's intended
for use by general public. Be sure to change ada0s1d to match your
system by the way.
