Yes, of course.

Yes, that's the solution to my problem. I've moved the setup stuff of 
bi_enetaddr and bi_ip_addr far behind the whole init_sequence loop and the 
relocation env_relocate(). I think and hope, that will be save enough for the 
future development.

OK here is the patch (attechment). Wolfgang, could you put it into the CVS 
repository?
