This read-write enumeration sets or reports whether a package was, or should be, installed in single or multi commit mode, controlling the transactional scope of the install/commit process. Admins choose the appropriate mode depending on whether they want a package activated in one atomic step or committed incrementally across multiple stages. For example, an admin rolling out a package across several dependent components might choose multi mode to commit each component's changes in stages, rather than single mode which commits everything as one all-or-nothing operation.
