I guess since there is an established rotation for new sysres sets, they probably could run with it R/O now and switch to R/W when required. The mode change wasn't even allowed until z/OS 1.5 (or z/OS 1.4 with a PTF). That being said, I have never seen a single problem caused by having the sysplex root mounted R/W 100% of the time. If anyone in z/OS unix development is listening (or Peter), I think this would make a good "best practice" health check.
