That's the easy part. |

Column 1 in /etc/fstab identifies which partition is to be mounted. |
| 12 |
Identifiers need to be unique. |
| 13 |
|
| 14 |
Device names in /dev/ are no longer stable, they can and do move around |
| 15 |
and change. |
| 16 |
User-defined labels are a good choice but users can and do re-use the |
| 17 |
same labels. |
| 18 |
All filesystems generate a GUID for themselves and these are guaranteed |
| 19 |
to be unique in the universe, so simply put it in column 1 and mount |
| 20 |
will never ever get it wrong. |

Ubuntu takes this approach to be able to give guarantees about |
| 23 |
installers. It works well. Until you find you want to edit fstab by |
| 24 |
hand. |
