What should it do with that?
If you provide some way for a distro to fill in "foobar linux 188.8.131.52"
maybe. But just Linux or even Linux x.y.z would be wrong because the same kernel
version can behave very differently.
But it would be better to define specific feature flags for
specific needs that actually mean something.
I think the conclusion I have come to is that this really belongs as a
small program that runs at startup. That's not significantly different
than having it done in the driver. I can help you write it, if you like.
I think Andi is right here. "Linux" may mean something to your
management software. Some other management software may want "Linux
x.y.z". Another may want "SuSE Enterprise Linux x.y". It's impossible
to be general enough in the kernel.
I know there were some concerns with the security aspect, Can you please let me know what kind of security holes we could be looking at ?
I don't think there are any security problems. just forward/backward
compatibility problems, as the ACPI experience shows.
I had mentioned possible security issues with having some daemon that
identified the system directly over IP. I don't think there are any
issues with IPMI, at least not any more than you already have with IPMI,
and it's reasonably secure for what it does.
