We should rather not rely on this.

I think many boards contain board-specific code to manipulate the
environment, especially on first boot (and resetting the env usually
makes the next boot a "first" one).  You cannot scan all board
specific code for such actions, or implement any generic handler for
this.

[Well yes, maybe one could rewrite all such board-specific code into
some common "first boot handler" that could be called from a central
place,  but who should do that?

Best regards,

Wolfgang Denk

As usual, this being a 1.3.x release, I haven't  even  compiled  this
kernel yet. So if it works, you should be doubly impressed.
