Filesystems have permissions, partitions don't. Files and directories have
owners, partitions don't.
/tmp and /opt are filesystem locations. They may or may not have partitions
mounted to them. Regardless, the chmod command affects the directory
entries on the filesystem, not the partitions.
The currently-running OS may restrict its "unprivileged user" from
accessing the hardware directly. That's not the partition's fault.
