Operating system control of directory events with dynamic program execution

A method, comprising:

• providing, via a processor within a memory, a directory operational block data structure that allows configuration of a directory of a file system at an operating-system level with at least one executable program to be executed in response to configurable operating-system level directory events associated with the directory, where the directory operational block data structure is configurable with at least one permission criterion for authorization to attach programs to the directory operational block data structure for execution in response to directory events;
• attaching, within the directory operational block data structure in response to determining that a user issuing a configuration command for the directory operational block data structure has permission to attach the programs to the directory operational block data structure, a first program to execute in response to a specified directory event;
• and
• executing, at the operating-system level in one of a safe mode and a journaled mode, the attached first program in response to detection of the specified directory event.
