Right, for v2.

I'll remove that from the upstreamed patch. I'll keep it for me for my ISP
router to give me consistently the same IP address through DHCP.

I'll try for v2, yes.
Speaking of which, this implies one redundant information :
 - the env/init/mtdpart-nor to define partitions (including bareboxenv)
 - the code to add env0:
   devfs_add_partition("nor0", SZ_2M, SZ_256K, DEVFS_PARTITION_FIXED, "env0")

This means that if the partition scheme changes, barebox binary has to be
recompiled and reflashed. Isn't there a better way ? (that was what my
mtd_env_override tried to do btw).

Cheers.
