Accepting request 308347 from home:jengelh:branches:Base:System
it's not really SLE-only, so I opted to name it udev-persistent-ifnames instead of udev-branding-SLE OBS-URL: https://build.opensuse.org/request/show/308347 OBS-URL: https://build.opensuse.org/package/show/Base:System/udev-persistent-ifnames?expand=0&rev=1

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.
