The renaming problem still exists.

I tried to workaround it by changing 10-netint.link as follows:

10-netint.link:
[Match]
MACAddress=00:01:2e:77:a5:45
Name=eth*

[Link]
Name=netint
WakeOnLan=off


As the vlan interface is named kbs this should not match, but the physical 
interface which starts with eth0 should.

But the vlan interface still ist renamed to renameX and later udev wants to 
change its name into netint, so kbs matches.

The systemd-doku says:
	"A link file is said to match a device if each of the entries in the 
	"[Match]" section matches, or if the section is empty."
