I have not deleted my ifcfg-link script (mine does not have the .sh 
extension?)  I just made the eth0

But then I have cubie 2 and 3 (truck).

Per the Network Manager list:

nmcli con mod $ifname ethernet.cloned-mac-address "$your_mac"

We did have an interesting discussion on the historical origin of these 
names and why they will remain as they are.

Are you running on a sata drive with only uboot on the uSD card?  I 
would like to know how sata performance is.  Does it even boot (given 
your usb hang issue) from sata?  I remember way back Hans working on 
getting usb sata (in general) boot working for Allwinner, but I never 
tested the later uboot versions.
