One side remark (David surely knows, but his text below may not be explicit
enough)
when you'd need a real IPL with disks starting at cylinder 1, just copying
cylinder 1 to 0 will not be sufficient. One needs to move the whole disk
up one cylinder. So DDR: COPY 1 END REORDER 0

Not necessary. MAINT usually has full-volume MDISK defined for 540RES,
