| 31 | <para>A tmpfs mount is added at /dev/shm to comply with Posix shared memory

| 38 | <para>There are other lines which you may consider adding to your fstab

| 41 |

| 42 | <para><screen>devpts /dev/pts devpts gid=4,mode=620 0 0</screen></para>

|

| 44 | <para>Another example is a line to use if you intend to use USB

| 45 | devices:</para>
|

| 46 | <para><screen>usbfs /proc/bus/usb usbfs defaults 0 0</screen></para>
