Re: NFS boot fails with ip_output.c rev 1.261 (Rin Okuyama) writes:

The change in ip_output.c prevents the use of a recently configured
interface because now you have to wait for duplicate address detection
to finish.

The NFS boot code has a hard coded delay of 3 seconds between configuring
the interface and using it to start the NFS mount operation. That's
too short for DAD to complete. As the mount operation is done with UDP
the code fails immediately.

The slow DAD mechanism creates more problems than it solves.
The NFS boot code should handle such errors gracefully.
