I'm not attached to the ghost term, but what it describes is here to stay.

This state has a special treatment in the daemon : paths in this state are kept in active state in the DM, instead of proactively being failed. This is for the hwhandler to be given a chance to activate a PG with only ghost paths in it.

If you come with a better term, I'll sure consider it. Maybe "spare" ?
