摘要：
A mechanism is provided for isolation of device namespace to allow duplicate or common names in root volume group workload partitions. The mechanism creates a scratch file system that contains enough information to create an execution environment for a workload partition and information about which physical volumes to use for the root volume group file systems. The mechanism then populates the root file systems on a disk in the global space. The mechanism boots the workload partition from the scratch file system and configures the devices to be exported to the workload partition based information in the scratch file system. The mechanism then renames the logical volume names to the traditional names. The mechanism then temporarily mounts the root volume group file system onto the scratch file system.
