Thanks everyone. I didn't know about the chmount command. My main problem was always creating a mount point for product specific file systems. Having a way to make the root file system Read/Write temporarily, is the best solution.

If you are not in a shared file system environment (you don't have SYSPLEX(YES) in your BPXPRMxx) then you can't share anything other than READ only. However, whether in a shared file system environment or not, why would you want the z/OS root mounted anything but read only? It's an accident waiting to happen if you do. z/OS already gives you a way to dynamically activate maintenance when you can and it doesn't involve writing to the IPLed z/OS unix root.
