Comment # 1 on bug 931165 from Dr. Werner Fink

AFAICR and AFAICS the systemd (aka systemd-210) from Base:System:Legacy
includes several patches which exactly fix this:

     1021-udev-re-add-persistent-net-rules.patch
     1006-udev-always-rename-network.patch

btw: also the reporter, if really insists on the old naming scheme, could have
a look into the source codes of current systemd in factory.  Simply to make
patch 1021 work and to be aware that patch 1021 does oly switch back the old
naming scheme for SLES and not openSUSE.  For later case the kernel command
line option net.ifnames=0 may help to enable the patch 1021.
