No.

See the fdisk(8) or bsdlabel(8) programs for examples.

the sysctls return a "state picture", ie, they describe the way things
are right now.

Configuration happens by telling what change to make ("add this",
"delete this", "change this"), not by giving a complete picture
("make it look like this").

This would happen by users clicking on things, maybe specifying extra
parameters and then shipping it down with a g_ctl() call.

We'll burn this bridge later :-)
