I think I am narrowing down where the issue might be. I am seeing a 
difference when booting between a buster and a bullseye NFS ROOT.

I do the initial FAI imaging using a buster NFS root and install buster 
in /target. When I then run "chroot /target udevadm info 
/sys/class/net/eth0" I see about 27 lines including a bunch of 
ID_NET_NAME_* values.

I do the above again, but this time with a bullseye NFS root and install 
bullseye in /target. When I then run "chroot /target udevadm info 
/sys/class/net/eth0" I see only about 6 lines and, in particular, no 
ID_NET_NAME_* values.

I created the bullseye NFS root in the same way as for buster (I think). 
Why is there this large difference in the outputs of udevadm info?

Note that I used FAI 5.9.4 to create the NFS root for bullseye.
