Time: May 15, 1980 4:40 PMBy: McJonesAction: Equate PhysicalVolume.ID to same type in System

Time: June 28, 1980 5:23 PMBy: ForrestAction: Trim long. Eliminate procedures now defined in other interfaces, and ReGroup adding some comments about moving Procedures. Move [Get|Set][Logical|Physiccal]VolumeBootFiles to KernelFile, GetContaining PhysicalVolume to PhysicalVolume.

Time: July 13, 1980 9:15 PMBy: ForrestAction: Move most procedures elsewhere.

Time: July 28, 1980 2:33 PMBy: LuniewskiAction: Added nullSubVolume, SubVolumeUnknown.
