Abstract
A virtual configuration system, comprising a virtualization engine and a configuration engine, for the dynamic instantiation of configuration files is disclosed. A mechanism is disclosed that allows for transactional updates to a repository of configuration settings comprising multiple files. Configuration entries are stored in a first memory location and a copy of the entries is stored in a second memory location. A virtual configuration file that includes a virtual configuration for each entry is created and used to provide the operating system with path and location information regarding the configuration entries. Simultaneously and during run-time of the computer, the configuration entries stored in the second memory location can be modified. Once the modifications are complete, a second virtual configuration file is created referencing the configuration entries stored at the second memory location. The first virtual configuration file is thereafter atomically replaced by the second virtual configuration file.
