If you are using udev, and have configured the kernel for hotplug |

appropriate hotplug events, and udev will create the device nodes. |

Write udev rules to create persistent device names. |

An example: |

BUS=="usb", KERNEL=="sd[a-z]2", SYSFS{serial}=="300000005AF6", |
| 19 |
SYMLINK="%k", NAME="backups%e" |
