Or, she is following a long-standing practice to not allocate paging on cylinder zero. In ancient times, there were problems (perhaps lost in the mists of time) with VM using cylinder 0 on a real DASD. I vaguely remember problems related to allocation bit map when paging in cyl 0.
I still reserve cylinder 0 on every DASD as PERM space and specifically do not allocate any MDISKs, CP area, etc. thereon. One cylinder per disk is really inexpensive compared to a (very unlikely, but 100% avoidable) system outage.
