What does it use the NVRAM for? Is the meaning common across all OSes that use
it? How many bytes are used? Does the data actually need to be changed, or
would initializing it to a constant work?
If the data is static, I'm wandering whether it would be better to store this
data explicitly as part of the domain config rather than referencing another
file.
Thanks,
Ian
