Patent ID: 8650579

Claim:
A method comprising: executing, using hardware and within a production process container, target production processes of a first instance of a target program, said first instance being all or part of or executing on an operating system; executing, in an installation process container separate from said production process container, an installation process to update said target program; attempting, by said installation process, an inter-process interaction target program, said inter-process interaction being such that, if not blocked, would interfere with execution of said first instance of said target program; blocking, by at least one of said production process container and said installation process container, of said inter-process interaction so that said at least one installation process does not interfere with execution of said first instance of said target program prior rebooting said hardware during or after updating said second instance of said target program; and without shutting down the first instance of said target program: creating, by a file system manager executing within said installation process container, a clone volume; copying, by the file system manager, an original root volume group including said first instance of said target program into the clone volume and redirecting, by the file system manager, calls from the original root volume group to the clone volume.
