| - | The third column shows either "(ro)", which stands for "read-only", or "(rw)", which stands for "read/write". OpenOS only supports these two access permissions, and they are filesystem wide (as opposed to more modern filesystems that have separate permissions per directory and per file even under the same filesystem mount point).

| - | The last column displays the filesystem's label or the filesystem's component address in the case it has no label. Loot disks always have their loot disk name as the filesystem label. You may notice that the filesystem mounted on `/mnt/0e7/` in my example has a very long "label". This is because I am using a brand new tier 1 hard drive which doesn't have a label yet and thus its address is displayed which causes the terminal to wrap the text. | + | The last column displays the filesystem's label or the filesystem's component address in the case it has no label.

| - | You may also notice that a few of the filesystems are mounted multiple times. The behavior of OpenOS is to automatically mount filesystems in the /mnt directory, with the first 3 or more unique letters of its address as the directory name. Some components get a special mount location, such as the filesystem that booted the system. In this case, the floppy disk on /mnt/bc3/ is the boot filesystem, and thus is the rootfs (on /). To help make the listing of `mount` more readable, I programmed it to sort the listing by address. | + | You may also notice that a few of the filesystems are mounted multiple times.
