[sles-beta] Lan adapter naming, a work around

[Joe Doupnik]

     Beta 2. As many of us have discovered, the names of lan adapters 
are whimsical and not what we want, and at this moment the GUI version 
of YaST is incomplete in the lan adapter area. The notes on systemd's 
role in this are amusingly bad news; impractical.
     There is a way with Beta 2 to regain eth0/1/etc. Use the text mode 
YaST, Network Devices section, go to the Hardware tab, see the upper 
left corner menu which is titled Udev Rules (that will be crystal clear 
to non-gurus...). Open that, see the partial systemd device name (such 
as ens32), erase it and type what you want.
     What happens? Magic. We get the device names we want. And a 
70-persistent-net.rules file is created in /etc/udev/rules.d with the 
regular MAC address and name configuration lines which otherwise have 
become lost/discarded/rejected by the systemd material. Also, ifcfg-ethN 
files in /etc/sysconfig/network have correctly matching names.
     Another amusing sighting in this area. The first lan adapter is 
described as Ethermet Network Card, and the second as 8254EM Gigabit 
Ethernet Controller (Copper). Both are just regular ESXi v5.5 Ethernet 
devices.
     Points to those who can find where systemd creates its Ethernet 
adapter name patterns. I gave up looking.
