Owner's Manual

When a system is booted from SBUU, the /opt filesystem is linked to /tmp filesystem. Some syscfg and
racadm functionality use /opt extensively. If user mounts any other device (like a USB drive) to /tmp and
issues racadm or syscfg commands, the files in /opt will be no longer visible and the commands fails.
User is advised to create a temporary directory under under /mnt and mount the USB devices there
instead of mounting to /tmp.
