System-level environment variables. The system-level environment
variables are stored in a global environment space that is
persistent across IPLs and is not associated to a particular job.

That only needs to be done once, right? (i.e. not in QSTRUP?)

Yes. Just set once... whenever, wherever. As the doc snippet says, the storage for the System-Level (*SYS) Environment Variables is "persistent across" system end\start activity.

However... The setting is a /change/ to the system that should be included in the System Change Management, to ensure that the desired setting is established again when appropriate; e.g.upon migration to another physical system. Some CM implementations may activate that within the QSTRUPPGM which may have an always-set path or an optional path based on conditional logic that recognizes a change for which a [re]set is deemed appropriate; e.g. a value retrieved from an object that is not part of the Backups that would be used for Disaster Recovery, such that if the object does not exist or the value mis-compares to the expected, then the optional path effects the [re]setting along with the creation and\or resetting of the stored value.
