| 42 | ## The wwid line in the following blacklist section is shown as an example |
| 43 | ## of how to blacklist devices by wwid. The 2 devnode lines are the |
| 44 | ## compiled in default blacklist. If you want to blacklist entire types |
| 45 | ## of devices, such as all scsi devices, you should use a devnode line. |
| 46 | ## However, if you want to blacklist specific devices, you should use |
| 47 | ## a wwid line. Since there is no guarantee that a specific device will |
| 48 | ## not change names on reboot (from /dev/sda to /dev/sdb for example) |
| 49 | ## devnode lines are not recommended for blacklisting specific devices. |
