forked from pool/udev-persistent-ifnames

This package, when installed, disables the default "Predictable
|
||||||
|
Network Interface Naming" scheme[PNIN] in udev, and switches it to a
|
||||||
|
first-loaded-first-named, reboot-persistent scheme.
|
||||||
|
|
||||||
|
[PNIN] http://freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/
|
||||||
|
|
||||||
|
Differences from PNIN:
|
||||||
|
* Re-enumeration when the L2 address changes.
|
||||||
|
* Interface names are not - and cannot be - derived from another property
|
||||||
|
like PCI bus address.
