By providing /u or /j switch on mount, the virtual CD-ROM class driver
will break the associated signatures on read so that FSDs cannot recognize them any longer.
It allows you managing virtual drives, mounting images, ejecting images, and so on.
It will load the driver when required.
It's less features complete that the MS GUI implementation.
I'll implement them later on, it can be quickly done.
What's missing: UDF/Joliet suppr and persistent mounts
