thanks for the fast response. However, it does not explain, why both machines 
are different.

Both machines were installed by DVD and both got the same settings and package 
versions. Both machines were installed by the same DVD and then of course 
upgraded by the internet. And both are running debian/testing. 

The only thing, which IMO would explain it, that the EEEPC is newer than the 
other one. But then the hardware must talk to the operation system and give 
more information to udev or systemd. Does this do such things? There was 
something mentioned in the doku, but I did not quite understand, what the doku 
meant.

And if enps10 is the "new" kind of naming network devices, is it then 
recommended to edit all configurations and change the entries from eth0 to 
enp1s0?

This would also mean, I guess, either 70-persistent-net-rules must also be 
edited or should be deleted. 

But all this makes not clear to me, what makes the decision, when enp1s0 or 
when eth0 is going to be created on a system at boot.

Thanks for reading.

Best
