  Yes. I've not tried that, but guessing it could be used as a 
workaround for something like a zvol-backed image where the zvol is 
created after the sysctl is set.

  However, what is really needed is something like a blacklist that can 
prevent specified devices from being seen by GEOM at all, since the 
internal structure is only relevant to the guest VM.

later,

Peter.
