I have begun in the small to implement a userland GUI for geom
So far it can only display the sysctl output of confdot,
but the idea is that it should be able to display what something like
this: sysctl -b kern.geom.confdot | dot -Tps - && gv -
Just in realtime or close to.
In version 42 it should be able to configure geom to, by entering data
in the gui.
