| 106 | Tmpfs is a file system which keeps all files in virtual memory. |

| 110 | space. If you unmount a tmpfs instance, everything stored therein is |

| 126 | If you've selected TMPFS, it's possible that you'll also need |
| 127 | this option as there are a number of Linux distros that require |
| 128 | POSIX ACL support under /dev for certain features to work properly. |
| 129 | For example, some distros need this feature for ALSA-related /dev |
| 130 | files for sound to work properly. In short, if you're not sure, |
