Finally add the long awaited Mount Point Manager (aka mountmgr).
It's not complete yet, but will do most of the job it's been designed for.
What's missing is some dos volumes handlers, complete database support (local - registry - is complete, remote - files - is not).
It handles NTFS properties like reparse points.
It also handles devices with drive letters and those without drive letters (by using their unique ID).
Devices removal/arrival is detected through notifications (might be an issue).
Some work will have to be done in storage stack to fully support it.
Most of its IOCTL have been implemented (it's possible, for example, to notify a volume arrival through them, in case notifications don't work).
There's still some work to do on it to have it complete and fully implemented.
Enjoy!
