Abstract: One embodiment disclosed relates to a method of automated registry clean-up for an operating system of a computer system. Interfaces on which each module depends is determined, and a module is marked as obsolete if the module depends on an interface that is non-existent in the operating system. Configuration data is removed from a system registry for modules marked as obsolete. Other embodiments are also disclosed.

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 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: In one configuration, a method for operating a computer includes booting an operating system having a plurality of tunable kernel subsystems; storing a representation of at least one base tunable having a set of inheritable properties in a memory of the computer; and storing, in a memory of the computer, a plurality of representations of instances of at least one of the stored base tunables, each instance including at least one inheritable property of the stored base tunable, wherein representations of at least a first instance and a second instance are stored at different memory addresses. The first instance and the second instance include a plurality of values, and differ in at least one corresponding value.

Abstract: A method for operating a computing apparatus includes specifying proposed changes to a plurality of tunable parameters of tunable kernel modules determining whether application of the changes would violate a set of constraints; and effectuating either none or all of the changes depending upon whether the changes were determined to violate any or none of the constraints, respectively.
