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