Abstract: Systems, methods, and devices are provided for testing commands in a cluster environment. One embodiment includes saving an original system state of two or more targeted cluster members by invoking a first operation with a testing tool and automatically testing the system states of the two or more targeted cluster members on which a command is run.

Abstract: Systems, methods, and devices are provided for kernel configurations. One embodiment includes a kernel configuration tool, a system file accessible by the kernel configuration tool, and means for automatically detecting and moving a kernel configuration in association with boot and shutdown routines.

Abstract: Systems, methods, and devices are provided for transactional kernel configuration. One embodiment includes a kernel configuration tool, a system file accessible by the kernel configuration tool, and program instructions executable by the kernel configuration tool to immediately and persistently apply kernel configuration changes a manner that ensures a transactional kernel configuration change.

Abstract: Systems, methods, and devices are provided for kernel configurations. One embodiment includes a kernel configuration tool, a system file accessible by the kernel configuration tool, and means for recovering kernel configurations without the use of a manually creating a “known good post update” kernel configuration.

Abstract: Systems, methods, and devices are provided for handling changes in module load status. One embodiment includes a module having an object file and a module preparation script. The module object file can implement a function in a program application. The module preparation script file can be associated with the module object file to provide information to prepare the program application for a change in the load status of the module.

Abstract: A dynamically loadable stub module, associated with a dynamically loadable kernel module (DLKM) includes a base stub module, means for defining DLKM data structures and wrapper functions, means for defining load and unload routines, means for defining metadata structures, means for allowing dynamic loading by DLKM infrastructures, and means for generating a dynamically loadable stub module object file.

Abstract: Systems, methods, and devices are provided for handling module symbols. One embodiment includes a module link tool having a processor, a memory, and program instructions provided to the memory and executable by the processor. The program instructions are executable to translate a particular type of information associated with an object file into instructions to provide to a linker utility.
