* inspected, to be inspected for a specific Windows system

*
* Solving 1 properly would require a new API at a minimum. We
* might be able to fudge something practical without this,
* though, e.g. by looking at the <partition>th partition of
* every disk for the specific windows root.
*
* Solving 2 would probably require a significant refactoring
* of the way filesystems are inspected. We should probably do
* this some time.
*
* For the moment, we ignore all partition information and
