Some of the system are loaded from u-boot. We can technically change the
environment, but that would not be persistent. Product requirement is that the
default (hard-coded) environment has to be the one that is used. And changing
u-boot in those systems is more difficult than getting an audience with the
Pope - believe me, we went through that. Unless there is a fatal problem,
it simply won't be approved.
On x86 systems, which are booted through grub, we have a similar problem.
The boot menu is secured and for all practical purposes untouchable.
All that makes it much simpler to carry a one-line patch to remove the output
from the log. I may try to do without it and keep the message, but I am quite
sure that someone will complain and we'll have to do it.
