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: Various approaches for managing kernel configuration files in a cluster computing arrangement are disclosed. In one approach, a first set of kernel configuration files are installed networked storage, and a first node is booted using the first set of kernel configuration files. A copy of the first set of kernel configuration files is stored in networked storage as a default kernel configuration in response to an administrator initiated first operation. In response to an administrator-initiated second operation a copy of the default kernel configuration is stored as a second set of kernel configuration files for a second node of the cluster. The second node is booted with the second set of kernel configuration files.

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.
