Description

I really don't like that I can mistype something and vaporize datasets, and even entire pools. I would like to propose a property defined for datasets, zvols and pools that basically says 'if this is set to ON, any destructive operation will require use of the -f flag'. Thinking of destroying datasets, zvols and pools. Maybe snapshots too? This could really be a totally userland abstraction. What do y'all think?
